[Narayana B]

Hi,
It's a query , please help me here, i am bit worried as well.

I am in india currently, never used H1B visa after stamped.
I have H1B  i797 petition and visa stamped on 16/02/2018 in india, on employer(Xyz), and valid until Aug'2020.

Now i am planning to transfer to another employer(Pqr), they will file my new petition, do i need to go for stamping again in india or shall i use old visa and, i can travel with old visa.

 

There are should not be any problems at port of entry, uscis etc?
