1. Planning to transfer from H1B to H4, I-140 approved with Jan2015 priority date. Can I keep the priority date after I change to H4? Intend to come back to H1 after few months. 2. Currently I'm 7 months pregnant and I work for a consulting company (employer) on H1B visa, Can I take maternity leave on H1B? If yes, for how long? will it be a paid or unpaid leave? If not do I need to convert status from H1B to H4? If yes, can I change it back to H1B and work again or need to apply for a fresh visa?
Here is an interesting question, if I am on H-1 and I convert to H-4, does that kill or affect my priority date ? Answer is no. If you were on H-1 and you had filed a Green Card, you got a priority date and I-140 was approved now you changed to H-4 that does not kill your priority date. That's not the problem.
And the second part of the question was can I take maternity leave on H-1?
