Im a NATURALIZED American citizen . Can i recieve a citizenship of Another country with out USCIS revoking my US citizenship?

A US citizen doesn't necessarily have to give up US citizenship to become a citizen of another country.

My friend has H1B with company A and started working. In mean while his company is sold to other company B.

Depending on the circumstances of the sale, a new petition might be unnecessary. Suggest your friend contact an attorney.

I suspect a fraud.

I Have J1 status, now working as a visiting scholar in neuroscience Laboratory, Can I change my laboratory to another one?

The new laboratory would need to agree and would need to create a new DS-2019 for you.

I have VAWA approved( F2A), right now I'm on H1B in USA, when to file for GC, do they ask about Qs regarding previous marriage?

The biographical G-325a form asks about prior spouses. You must submit this form along with your I-485.

Travel abroad while H1-B Amendment Pending

Suggest you consult with an attorney.

What is the official name of the interview ICE makes when a person is detained?
