I am in 7th year of H1B; At the end of my 6th year, I changed employers from X to Y and got 3 years extension based on approved I-140 filed by old employer X. In my 7th year I went to India and got visa stamped based on new employers I-797 and old employers I-140. Now My old employer X has revoked the I 140. My question is if I travel now, will I have a problem considering the I-140 based on which I had got the H1B approved beyond 6 years has been revoked? My new employer Y has yet to start my GC process.
