Hi, my friend planned to go abroad to apply for H1B visa at first. However, he changed his mind after H1B approved.

The question is:" Can he change his status from B2 to H1b by filing form I539 based on the H1B approval?"

( H1B was approved for oversea processing.)

some one told him he must ask his employer to file another I129.
Is that true?

Thanks.
