Regarding L1 visa

[kaiju8]

Hello everyone. First of all, thank you for considering your time to read my post.

I wanted to ask about L1 visa type used to issue visas to managers or above in private firms. I have primarily 2 questions-

What is the criteria for the L1 visa type ? https://xender.vip/

Is the process of getting green card easier or doable than H1B?

I'm a working professional from India and would really love to go for an onsite opportunity in future through L1.

Thank you for your time.
