Location Amendment question

I’m in location A and the validity of the visa is August 30.

I have filed an extension plus amendment to a new location B for the same employer and the same client and it is in process under normal processing which is taking 7 months. Filed in April 2024.

When should I start working from the new location, can I wait until the petition to
New location is approved or should I move there by Aug end? Please advise.

You can start working at a new location after you have filed the amendment.

Anil- My question - till when I continue in the old location? Can I wait until the extension and amendment is approved. Or should I move by Aug. Please advice. Thanks!
