I have a fear that my employer may revoke an approved I-140. How long does it take the USCIS to review his application to revoke the I-40 and grant the application.
----------------depends on the service center when they look at the letter of employer to revoke the I-140 and I-140 revoke date will be the date USCIS recieved employer letter to revoke I-140.
Any ideas from your own stories is highly appreciated.
