H1B Petition is still valid or not?

USA H1B Visa
#1

Hi,
My H1B approval came on 28th january 2019 valid till 31st march 2019 only.
I got my VISA stamped/approved on 23rd Feb 2019 and now because of some reason I am not able to travel within my VISA approved dates.
This would have been my first travel to US.
Can anyone help me with below queries:

  1. Will I be able to file for extension even without travelling to US even once?
  2. Is my petition still valid even though I have not used it ?
  3. A camp exempt petition can be filed for same petition or do I need to file a fresh petition now?

Yes. You cant file extension by yourself. Your employer should file for it.

No.

Its not CAMP, its CAP. Yes, you can have an extension filed under CAP -EXEMPT

Thanks for your response and correction :slight_smile:
Just one more concern…In my case for any future plans do I need to again through complete lottery process ?
