I was working for company A which processed my GC. I got my i-140 approval with company A and after 6yrs in US, got H1 extension for next 3 years with same company. In my 7th yr with company, Company A got acquired by Company B and I had to join another Company, Company C, which transferred my H1 and got extension for next 3 years. Now if my I-140 is revoked by company B, what will happen to my H1 and I am planning for trip to India, will I have any problems with Stamping of Visa, since the I-140 which is basis for all my H1 extensions got revoked? Please let me know
