I am currently on H4 visa and my spouse have applied for his change of employer from Company A to Company B in Apr 2nd week 2007 regular processing. My H1application was filed under premium processing and was approved (known via email) on April 18th 2007.
We did not apply for my H4 visa application (along with my spouse's H1 application throught company B) as I had already filed for my H1 application for Oct-07.
So right now I have two visas: H4 visa till 2010 Jan 31 as a dependent on my spouse's Comapny "A" extended H1 visa which will no longer be valid once he joins Comapny "B" ie new company and my own H1 visa active from Oct 2007 onwards. Also, on my passport I have a visa stamp till 2007, Jan 31, though i have valid H4 status (i-94) because of extended h4 visa .
Having said all this, let me come to my questions:
1. I want to go to India for a month or so and come back before Oct 1 so that I can visit family members before my job starts. Now because my H4 stamp on passport was only valid till 2007, Jan 31, do I need a new stamp?
------------------YES if you want to enter on H4 status
2. If yes, and if I am planning to come by July beginning to US , does my H4 visa application also needs to be filed from company B..ie my spouse's new company before I visit India?
----no, you will get new H4 visa stamp from US consulate based on your spouse H1 approval of B
3. If yes, would it better to convert my spouse's H1 application from regular to premium processing so that when I visit India, say in June beginning for one month.
-------------YES, so that you have his H1 approval notice for H4 stamping
4. Also(most important question for me), say if I get my H4 visa stamp from India, would it jeopardize my H1 visa which has been approved already.
----------------if you enter on H4 then you will get I-94 based on H4 and will not be able to work. to enter on H1 status you need to go out then enter on H1 by getting H1 stamp.
