Currently, my H1B visa is going to be expired on 1st APR 2017 and few days my back , got the stamping done for my wife and kid and they also got the visa till 1st APR 2017. Now , I am starting extension process for me and my dependents .
They are going to travel on Feb 2nd ,so wanted to check if there is any problem for them during their transit if new extension is filed and they are travelling on existing visa which is valid till 1st APR 2017
