If company-B files for your H1B transfer then your H1 extension will also happens automatically if its getting expired.

Check the I-129H form for the date they requested for your H1b to be effective. It should mirror the date on the LCA.

Immigration and Proxy Marriages Any Help will be greatly appreciated

Proxy marriages do not work for immigration. Common law ones do, if the marriage is legally recognized where you became married.

Will EAD be denied because the IC has not been served by USCIS yet?

Could be it will be denied. You will need to make an argument that the clock should not be stopped.

I got NVC case while I am in USA am I allowed to stay after my OPT will expire, am I allowed to go and come back to my country.

No, the approved visa does not give you any status until and unless they issue you the visa and you immigrate to the U.S.

I applied for my VAWA pention about 1 1/2 ago and was approved but havent gotten my biometrics appointmnet why is that.

You can follow up with them if you wish. Normally biometrics are for the I-485 adjustment of status, not for the I-360 petition.

The first require all fees to be paid and they process the forms for the affidavit of support and immigrant visa application, before they send it...

Denial letter

Perhaps the documents revealed you were not eligible for the benefit you sought.

Immigration

There is no violation of the U.S. immigration laws to travel from one state to another.

Departed the U.S 2 years ago, now with an approved petition. It's 1-2 months to priority. Can I still file I-601A on March 4th.

If there is a priority date at all, he cannot file the I-601A. That is only for immediate relatives, and immediate relatives have no waiting list...

If the police know you are going to be there, they can arrest you there.
