H4 visa query

[adorableabhinav]

Hello Forum,

 

I (husband) am working in USA. My H1B is expired and my employer has filed extension for me. My wife is on H4 and her H4 extension is filed too. I am expecting decision on my petition in next 2 months. My wife is planning a vacation to India, My question is

 

1) Do I need to wait for decision before her travel ?

2) In case she leave without having approved petition in hand, is it okay for her to travel back to USA once I my petition is approved.

 

Please advise. Thanks

Abhinav
