H1b transfer if the visa is under 221g?

[keerthan]

Hi Rajiv,

I have an h1b visa approved with employer A under the client model, but no client employment letter. so now I'm booking a visa appointment for h1b which has a very good chance of getting 221g refusal.

if I get 221G, can I transfer my H1b to a new employer - B, and book a fresh visa appointment with new approval? Will my previous refusal/221G affect my new visa interview?

thanks in advance
