L1 Blanket Extension Question

[anushsa21]

Hello 

I am currently in USA on L1B Blanket (first 3 years) with PED: Dec 2020 and I94 Expiry: Jul 2021. I have the below questions and would appreciate assistance.

1. When am I obligated to go for the extension? Before my PED or before my I94 Validity?

2. Is Canada/Mexico consulates accepting appointments for blanket extension before 31st Dec 2020?

3. If I am to go for a blanket extension in Canada/Mexico before 31st Dec 2020 (if no cancellations), will I be allowed to re-enter if visa is approved? Or will my entry be denied based on Jun 2020 proclamation? I was in US with valid status when the proclamation was signed.

Thanks for your help.

You can apply for L1-B extension from USA itself No need to go Canada and Mexico

As per my knowledge you can go Canada/Mexico for new L1-B, If L-B get approved and stamped then you can enter US without any issue.
