WIll I be able to use my old h1b visa to enter USA after I stayed here around a year and worked?

Question

I am no longer working in USA and settled abroad. My old h1b is still valid and i have possession of i-797 approval notice from new employer.

 

Earlier I had been working through new employer on H1b but I entered USA using old employer. 

Can I still use old h1b to enter now?

Answer 1

You have 2 options now-

1. Talk to the new employer's immigration lawyer (not a non-attorney in HR), and 
2. Get a new visa stamp.
