Backstory: I am on H1B visa working in the US currently and I switched my job last year to another employer. My H1B was transferred to this new employer that I am currently working with. My H1B expires in August 2018. My wife has H4 visa from my previous employer. She has traveled to the US once in December 2015 with the H4 from my previous employer. At that time, I was working with the new employer.
Situation: She is traveling on August 5th, 2016 and her visa is expiring on September 16th, 2016. Her visa is H4.
Is she ok to travel? Would she face any issues from the immigration since her visa is expiring soon?
Once she is here in August, I am planning to extend her H4 with this new employer of mine.
