h4visa to h1 b visa stamping questions

Hi.

I have a valid H4 visa stamped in my passport untill july 2016 , I Got my H1b approved with effective date on october 2013, Can i renter US with my Valid H4 visa on july last week or i want to go for stamping ,Please guide me

I assume you are outside of US and your H-1 was approved w/ consular processing.

So you have 2 options:

  1. Get H-1 visa stamped and enter on H-1 around Oct 1

  2. Enter on H-4 visa and file COS from H-4 to H-1
