Should I wait for my I 140 or try parallels outside . My h1b expires on 2021 currently
You are at the prime of your career. Don’t let a company dictate your life!
Just do it!
Wait for I-140 unless you already have an approved priority date
Exit on I-40.
Wait for i140 if it's less than 1 year away. Just do some side projects to keep yourself happy. See if they can be related to your team's work in some way.
Own your life.
