Can i join previous employer after H1b transfer?

Hello Experts,

I am corrently working in india for company XYZ ltd. I need Experts suggession.I have applied my H1b in the year 2014 through Company A and got visa in Jan 2015.Because of some personal issue i didnt leave for USA. Now i have resigned to my indian company XYZ ltd and will leave within 15 days.

I have got one more offer from Company B. They will initiate the trsnasfer of H1b while i im in india.

  • What will happen if transfer failes. Can i still join Company A?- What will happen if transfer approved. Can i still join Company A instead of Company B?- What will happen if transfer is taking time and i have to take decision. Can i join Company A without waiting for H1b transfer?

Note: I have never travelled to USA.

Thanks in advance.
