I have mandate international travel to make end of this month. H1-B transfer is in progress, since case is eligible for premium can expect the case status change by the time I return , how to handle this scenario at port of entry , at that time will be having I-797 of current company and the other one from transferring company.
It wont go into effect until you quit your current job and start the new job.
So at the port of entry I can come back with existing visa of current company rt ?
Yes
