Unused H1B and nationality Change:

[sparkyram]

Guys,

I got my H1B in 2015 lottery and H1B stamping is done in London,UK in my indian passport. I never travelled to US so far and my H1 petition is expired on 2016 Oct. Now my nationality changed from indian to british. My Stamped H1B is in my cancelled indian passport

1. Is my H1B still valid even after changing my nationality. ? do i need to go through any process to change my H1B from indian to uk passport ?

2. How long my unused H1B visa is valid ? I have never travelled to US after stamping .

If you stay outside the US after getting an H1 for more than a year, the clock resets and you are subject to the cap gap.
