My wife's h1b revoked by employer as she didnt join the company due to pregnency complications.She doesnt have any payslips from the employer though employer didnt let her join the client location for first 2 months. Her H1 to H4 conversion already approved. She's India now and will be coming to US on H4. Can she apply for H1B cap exempt from a different employer? If yes, What would be the common complications?
