H1B to COS B1/B2

Q

1. On H1B I797 & I-94 both valid till July 31,2009. Used 3 years of H1.
2. Last day on job May 22. Last pay I will get on 06/06/2009
3. Company said it will not file for H1 extension and will not revoke ( few weeks only).
My questions now-
1. Can I apply for COS to B1/B2 Efile now since I have car to sell and other stuff?
2. If I get a job before B1/B2 approval, how do I continue on H1 ?I assume my employer files for H1 extension.
3. If I get a job AFTER B1/B2 approval and also after expiry of H1 ( July 31), how do I get back onto H1?
4. If I go back to India,after expiry of my current H1, how can I revive this H1 with the current employer or New Employer?
5. If I apply for 2010 quota, can I be counted against old H1? or do I get new H1?( meaning 6 years?)

1. Can I apply for COS to B1/B2 Efile now since I have car to sell and other stuff?

You can apply for a COS from H-1B to B-2 using the I-539. You will want to do so before your the date on your last pay stub. You will want to include proof of your financial ability to take care of yourself and a separate letter explaining the reason you need to take care of things.

2. If I get a job before B1/B2 approval, how do I continue on H1 ?I assume my employer files for H1 extension.

Your new employer would need to file for a new H-1B extension for you. You can include evidence of your pending B-2 COS with that new H-1B filing. You may want to consider requesting premium processing so the new H-1B could be approved before the chance that your COS to B-2 could be denied.

3. If I get a job AFTER B1/B2 approval and also after expiry of H1 ( July 31), how do I get back onto H1?

If you have H-1B time remaining, you simply file COS paperwork on I-129 for new H-1B and COS from B-2 to H-1B. You should be fine for an H-1B extension as long as you have H-1B time remaining and your COS should work so long as you have B-2 time remaining.

4. If I go back to India,after expiry of my current H1, how can I revive this H1 with the current employer or New Employer?

You would have to file new H-1B paperwork and recieve a new H-1B approval. This H-1B paperwork should not be counted against the H-1B cap.

5. If I apply for 2010 quota, can I be counted against old H1? or do I get new H1?( meaning 6 years?)

If you are outside of the U.S. for one year, you can either file for remaining H-1B time (3 years?) or file for new H-1B under new H-1B cap.

question:what all documents I should send to support my application?

Posted on 01 Jun 2009

A.

In order to file for a COS from H-1B to B-2, you should include:

(1) Copy of your H-1B approval notice;

(2) Copy of your H-1B visa and I-94;

(3) Copy of the face page of your passport;

(4) Copy of 3-4 most recent pay stubs;

(5) Copy of recent bank statement(s);

(6) Letter explaining reasons why you need to stay in the U.S. as a visitor (i.e. apt./home, car, financial issues to resolve, commitments etc.)

Gvim editor new tips

da< - Delete the HTML tag the cursor is currently inside of the whole tag, regardless of just where the cursor is.
ci" -Change the content of a doublequote-delimited string.

da[ -  Delete the [] region around your cursor
vi' -  Visual select everything inside '' string
ya( -  Yank all text from ( to )

See :help text-objects.

:e! - Reopen the current file, getting rid of any unsaved changes
gg=G - AMAZING If you're coding, gg will bring you to the top of the file, and =G will auto indent (=) everything to the bottom of the file (G)
gq - reset the entire selection to be wrapped correctly.
=% -  Indents the block between two braces/#ifdefs
== -  Indents  current line 
d% -  delete till parrent  - cursor can be not on opening tag
ft - move to the next occurrence of t and 
tt - to move to the char before t 

Macros are stored in registers, these are the same registers that can be used
for copy paste. So say you record a macro to register q you can paste it into a
document with "qp, edit it, then select it and cut it back into the register
with "qd.

ГК стадии

стадии

0 - реклама. Для вас ничего не поменяется.
I - LC. Для вас ничего не меняется, кроме возможности продления H-1 за пределы 6 лет.
II - I-140 - Аналогично но начинаете указывать им намерения в анкете ну и по прежнему можете продлевать H-1. Если 140 аппрувлена но категория EB-3 (бакалавр) то продлевать можете сразу на 3 года за пределы 6-ти лет
III - I-485 (+ AP + EAD) - получаете нормальный документ для выезда (AP) и нормальный документ для внутренних нужд (EAD). Жена и дети получают возможность работать и иметь SSN.
III + 6 месяцев - можно менять работу.
ГК - не нужно больше суетиться и дети могут получать федеральную помошь на учебу и федеральные кредиты на учебу.

Если категория визы EB-2 или EB-1 то стадии II и III файлятся (все еще?) одновременно. Если EB-3 то между ними будет года 3 ожидания (все у того же работодателя и на визе).


Все правильно кроме, пожалуй, последнего. Время между непредсказуемо в случае Еб-3 - сейчас срок 7 лет исходя из бюллетеня, данные УСЦИС неполные и противоречивые, бэклог они посчитать не могут.


Дело в том, что начиная с 2006 года примерно поток EB-3 резко иссяк. И движение по оным годам будет очень нелинейным. Хотя... полный срок плавал от 2 до 5-ти лет, исходя из этого - срок по EB-3 вряд ли уедет за больше 6 - 7 лет (причем этот срок считается с подачи LC а не с подачи I-140, то есть если сейчас начнут, то и срок начнет отсчитываться), и вряд ли станет меньше 2 - 3 лет (сразу толпы набегут)...

Gvim editor tutorial: moving back trough changes

The changelist remembers the position of every change that can be undone. 
You can move back and forwards through the changelist using the commands:
g;
g,


You can view the contents of the changelist by running the command:
:changes

Vim also maintains a jumplist, 
remembering each position to which the cursor jumped, rather than scrolled. 
You can move backwards and forwards through the jumplist with the commands:

ctrl-O
ctrl-I

You can view the contents of the jumplist by issuing the command:
:jumps

you can follow the keyword  under the cursor with the command (ctags required):
ctrl-]

EventHandler event in usercontrol

First, we create a new, simple EventUserControl, with this code in it:

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="EventUserControl.ascx.cs" Inherits="EventUserControl" %>

Page title: 
<asp:TextBox runat="server" ID="txtPageTitle" />
<asp:Button runat="server" ID="btnUpdatePageTitle" OnClick="btnUpdatePageTitle_Click" Text="Update" />

All just text and server controls that we know. In the CodeBehind, it looks a bit like this:

public partial class EventUserControl : System.Web.UI.UserControl
{
    private string pageTitle;
    public event EventHandler PageTitleUpdated;

    protected void btnUpdatePageTitle_Click(object sender, EventArgs e)
    {
        this.pageTitle = txtPageTitle.Text;
        if(PageTitleUpdated != null)
            PageTitleUpdated(this, EventArgs.Empty);
    }

    public string PageTitle
    {
        get { return pageTitle; }
    }
}

We have defined a pageTitle container variable and a property for it. Then we have a new thing, an event. As you can see, it's defined much like any other kind of field, but it is a bit different. The theory about is explained in the C# tutorial, so we won't get into that here.
In the Click event of our button, we set the pageTitle field. Then we check if PageTitleUpdated, our event, is null. If it's not, it means that we have subscribed to this event somewhere, and in that case, we send a notification by calling the PageTitleUpdated as a method. As parameters, we send this (a reference to the UserControl it self) as the sender, and an empty EventArgs parameter. This will make sure that all subscribers are notified that the pageTitle has just been updated.

Now, in our page, I've declared our UserControl like this:

<%@ Register TagPrefix="My" TagName="EventUserControl" Src="~/EventUserControl.ascx" %>

And inserted it like this:

<My:EventUserControl runat="server" ID="MyEventUserControl" OnPageTitleUpdated="MyEventUserControl_PageTitleUpdated" />

As you can see, we have defined an event handler for the PageTitleUpdated event like if it was any other server control. In the CodeBehind of our page, we define the simple event handler for the UserControl event like this:

protected void MyEventUserControl_PageTitleUpdated(object sender, EventArgs e)
{
    this.Title = MyEventUserControl.PageTitle;
}

 YouBillWeb.AtlasHub.AdvanceCustomerDelete(customerID,onSuccessAdvanceCustomerDelete,onTimeOut,onFailed);
}

// Maintenance functions 
// -------------------------------------------  
// This is the callback function invoked if the Web service
// succeeded.
// It accepts the result object, the user context, and the 
// calling method name as parameters.
function OnSucceededWithContext(result, userContext, methodName)
{
    var output;

    // Page element to display feedback.
    var RsltElem = document.getElementById("ResultId");

    var readResult;
    if (userContext == "XmlDocument")
    {

 if (document.all)
     readResult =
  result.documentElement.firstChild.text;
 else
     // Firefox
    readResult =
  result.documentElement.firstChild.textContent;

  RsltElem.innerHTML = "XmlDocument content: " + readResult;
    }

}

// This is the callback function invoked if the Web service
// succeeded.
// It accepts the result object as a parameter.
function onSuccess(result, eventArgs)
{
    // Page element to display feedback.
    var RsltElem = document.getElementById("ResultId");
    RsltElem.innerHTML = result;
}

function OnSucceeded(result, eventArgs)
{
    // Page element to display feedback.
    var RsltElem = document.getElementById("ResultId");
    RsltElem.innerHTML = result;
}


// This is the callback function invoked if the Web service
// failed.
// It accepts the error object as a parameter.
function onFailed(error)
{
    // Display the error.    
    var RsltElem = document.getElementById("ResultId");
    RsltElem.innerHTML =
    "Service Error: " + error.get_message();
}

function onTimeOut(error)
{
    // Display the error.    
    var RsltElem = document.getElementById("ResultId");
    RsltElem.innerHTML =
    "Service Error: " + error.get_message();
}

if (typeof(Sys) !== "undefined") Sys.Application.notifyScriptLoaded();

How to create Setup project for Windows Service

How to create a Setup project for a Windows Service in Visual Basic .NET or in Visual Basic 2005

Create a Setup project for a Windows Service
This section describes how to create a Windows Service project and how to use a compiled Setup project to install the Windows Service.
Create a Windows Service project

1. Click Start, point to Programs, point to Microsoft Visual Studio .NET or Microsoft Visual Studio 2005, and then click Microsoft Visual Studio .NET or Microsoft Visual Studio 2005.
2. On the File menu, point to New, and then click Project.
3. In the New Project dialog box, follow these steps:
1. Under Project Types, click Visual Basic Projects or click Windows under Visual Basic.
2. Under Templates, click Windows Service.
3. In the Name box, type LogWriterService.
4. In the Location box, type C:\, and then click OK.
4. In Solution Explorer, right-click Service1.vb, and then click View Code.
5. In the OnStart event handler, replace the comments with the following code.

EventLog.WriteEntry("My simple service started.")

6. In Solution Explorer, double-click Service1.vb.
7. In the Properties dialog box, click Add Installer.
8. In the Properties dialog box for ServiceInstaller1, change the ServiceName property to LogWriterService.
9. In Design view, click ServiceProcessInstaller1 in the Code Editor.
10. In the Properties dialog box, change the Account property to LocalSystem. The LocalService value and the NetworkService value are only available in Microsoft Windows XP and later operating systems.

Use a compiled Setup project to install the Windows Service
After you complete the steps in the "Create a Windows Service project" section to configure the Windows Service project, you can add a deployment project that packages the service application so that the service application can be installed. To do this, follow these steps:

1. Add a new project to your LogWriterService project.
1. In Solution Explorer, right-click Solution 'LogWriterService', point to Add, and then click New Project.
2. Under Project Types, click Setup and Deployment Projects or Setup and Deployment.
3. Under Templates, click Setup Project.
4. In the Name box, type ServiceSetup.
5. In the Location box, type C:\, and then click OK.
2. Tell the deployment project what the deployment project will package.
1. In Solution Explorer, right-click ServiceSetup, point to Add, and then click Project Output.
2. In the Add Project Output Group dialog box, click LogWriterService in the Project box.
3. Click Primary Output, and then click OK.
3. For correct installation, you have to add only primary output. To add the custom actions, follow these steps:
1. In Solution Explorer, right-click ServiceSetup, point to View, and then click Custom Actions.
2. Right-click Custom Actions, and then click Add Custom Action.
3. Click Application Folder, and then click OK.
4. Click Primary output from LogWriterService (Active), and then click OK. Notice that Primary output appears under Install, Commit, Rollback and Uninstall.
4. By default, Setup projects are not included in the build configuration. To build the solution, follow these steps:
1. Use one of the following methods:
* Right-click LogWriterService, and then click Build. Then, right-click ServiceSetup, and then click Build.
* To build the whole solution at the same time, click Configuration Manager on the Build menu, and then click to select the Build check box for ServiceSetup.
2. Press CTRL+SHIFT+B to build the whole solution. When the solution is built, you have a complete Setup package for the service.
5. To install the service, right-click ServiceSetup, and then click Install.
6. In the ServiceSetup dialog box, click Next three times. Notice that a progress bar appears while the Setup program is installing the service.
7. When the service is installed, click Close.

To try find out asp.net performance leak/locks or why my .net app is slow on multiple requests :) ?

1.take memory dump and load it in windbg with "sos" as described  here.
Then you can load sos commands .cmdtree c:\debuggers\cmdtree.txt
3.Evaluate clr stacks for all threads by  ~* e !clrstack  
or by selecting Stacs/All managed Stacks from Sos Commands menu window.
as result you will see  call stack lists,similar stacks like for memory dump.
4.Look for System.Threading.Monitor.Enter or System.Threading.Monitor.Exit in page load stacks , that might indicate that static object is using 
that might cause slow performance for multiple requests.

5.to monitor sysncBlock use !syncblk commad
it will show who owns the lock and how many people waiting for it in "MonitorHeld" column.

"Info" column will  - contains thread number [thr] that locking, use  this commands:  
~[thr]s 
!clrstack 
to display locking stack and which give you a chance to  locate which procedure holding it. 

also debugging and preview of dump files will be available in Visual studio 2010.

How to find memory leak in .net application:

1.Create dump file of application process in windows , you can use this tool

DebugDiag (free tool from Microsoft)
Open it, go to "process" tab and select "create dump file"
2.  Download and install  
windbg  Start windbg and drag dump file there.
3.if it's dot.net you have to load sos extension , in windbg command line , type:
.loadby sos mscorwks
4.then  !dumpheap -stat you will get list of all .Net objects in memory/dump
if you want to get specific instances , you can hit:
!dumpheap -mt [addr]  - where [addr] is addr from left  column in windbg
you will receive list of objects loaded into memory , by dump out  do objects:
!do [addr]  you will dump specific objects with it's  properties.
when you do !do [addr]  when [addr]  of specific property you will get particular value of that property. 
5.if you dumped web-application and see aspx pages this is not good. 
you can get static objects by this command (it will show links on cache objects as well):
 !gcroot [addr]   where [addr] -- address of page in memory

As alternative you can use different analysis from [Analysis] tab in DebugDiag.
Memory Analysis gives a nice report.
