H1B Transfer

[devon9]

Hello, I was hoping to find some answers here regarding H1B transfer. I am working at University and I have potential offer from other university.

- How long does the visa transfer process take from cap exempt to cap exempt?

- What would be the approximate costs for transfer https://xender.vip/ ?

- Online it says you can start working once USCIS receipt is received, how long does that take?

Thanks in advance for your help.
