H1B Stamping Before the current i797 expiration date and before the i797(extension) s

[Maraju]

Hi All,

I got H1(was F1) and approved for 1 year in May-2016.

H1 Start date: - Sep-2016 and End Date:- Sep 30th 2017. I have not go for stamping yet.

Now I am planning to apply for extension in Apr-2017 and go for stamping in June/July after the extension is approved.

I will go for stamping in July-2017 and will come back US before Aug-2017. When I go for stamping, would I get stamping until 1st H1 i.e. Sep-2017? or would I get stamping until extension(assume 2 years) i.e. Sep-2019?

Appreciate your help ! Please respond with your suggestions.

Thanks

Raju
