Do I need to get Stamped? If So, Dropbox enough? :-
Timeline details as below...
I got H1B visa stamped oct-2014 with validity until oct-2017 with Employer A.
On Dec-2015, I transferred to employer B and got validity & i94 until Mar-2017 (no stamping done)
On Mar-2017, I got extension with validity & i94 from Apr-2017 to Mar-2020 with same employer B.
On Nov-2017, I am going to india and coming back on Dec-2017..
Do I really need to get stamped (Since I have i94 valid until Mar-2020 on my I129)?
If needed, Do Dropbox enough? (Since recent renewal within a year i.e; Mar-2017)
Please let me know.
