I am currently employed in the US with an approved H1B Visa (valid upto 2017). But, I am thinking of switching jobs. My question is : Will I be able to take a vacation outside the US while I am between jobs and then re-enter using the old H1-B Visa + the offer letter of new job ?
Now, in the longer run, I am aware that I'd have to transfer the H1B to new employer. But, it is not clear to me if I will be able to convince my new employer to initiate such a transfer before my formal joining date. Hence the question!
