H1B transfer with PO

[mhkraju]

I am planning to apply for H1B extension.

1. What are the documents required to apply for H1B transfer?
2. Do I need to have client or vendor letter to apply for H1B transfer?
3. Can I apply for H1B transfer only with the PO?

Advise me ASAP.

2. Do I need to have client or vendor letter to apply for H1B transfer?
>>> If the company that is applying for the transfer is a consulting firm, then YES.

3. Can I apply for H1B transfer only with the PO?
>>> No one will stop you from applying without the client letter. But if the client letter is requested by USCIS by sending an RFE, then you need to produce it to get the transfer approved.
