My wife is pregnant and she will be on maternity leave effective from 1/1/2020. Her project and H1B both end on 12/31/2019. She works in EVC model and don't have client letter to file H1B extension. Client agreed to take her back after 3 months.
Because we don't have client letter to file extension, her employer is saying that she can file for H4 COS and H4 EAD.
When she is ready to start working(after 3 months), even if H4 COS is pending, her employer says, we can file H1 and start working without leaving the country? Is this true?
