Regarding H1 B Visa

[Guru_Jeya]

Hello All,

I came to US during March 2011 for Employer A on H1-B. My Visa with Employer A is valid till Dec 26, 2013. Then i joined Employer B on Aug 2011 and transfered my H1-B. I am planning to go for vacation during Jan 2013. My Employer B told me go for stamping (not required though) because they told me that if my Employer A withdraws my petetion, it will be a problem in Port of entry.

1) Does this really happens? Do i need to go for stamping first for Employer B?

2) Now, i am planning to join Employer A again. Should i have to go for stamping during my vacation in Jan 2013 for Employer A again?

3) Incase if i stick to Employer B, and if i dont have to go for stamping, then on which company visa can my wife come?

Thanks
Guru

You can use your current Visa and B's petition to return to US. New Visa is not needed.

If your wife does not have a Visa, she can apply for it using B's petition.
