I am with Company A .Working for 1+ years.Now Company has re branded and moved to different name B .My I-797 H1B petition is under Company name A.

Now i am going to India and do stamping along with family.I have booked my interview.

1)Can i go with the Same I 797 for stamping under company name A ?

2)What all documents w.r.t to company name change should i carry

3)If i cannot go for stamping with Company A I-797 then should i book for another interview ?

Please clarify .Thanks in advance
