How many days min validity required for filing extension/amendment

Hi ,

I never traveled to US but my H1B visa is going to expire on this Oct 2016.Can I apply for extension until my visa expires? Is there any rule like we have to file the extension before 60 days of H1B expiry.?

If you are inside US, then extension document should reach USCIS office prior to current expiration date.

If you are outside US, then this can be applied even after the current petition has expired.

Hi saurabh

My case is similar
My h1 validity is upto December this year but I did not get chance to travel due to other commitments. Before what time I need to travel to US to extend my visa. Can I apply for extension even from India without traveling to US? Appreciate your help
