Role and education background? No transfer can guarantee 100 percent success rate but most of the time things work out
Rfe possible, depending your education, new job role etc. but rejection highly unlikely. Worst case even if it is rejected, google can refile and have it approved. I dont expect companies to take h1b rejection that easy(if they hire someone else no guarantee other candidate will not have same issue)
Yeah. Highest approval imo is sde to sde with cs degree
Is it a different job family?
