Previous employer letter L1B

[Dipayan Ghosh]

Do I need get letters from all my previous employers or just the last one. And in absence, can I take offer letter/ separation letters as evidence ?

I dont think it is a USCIS requirement, it might be presented as supplemental evidence to support your experience.

This is my opinion not legal advice.
