Sponsoring sibling / children to US

[fairyfloss 0]

I am planning to help my parents and sister who is a “special need” to come to US. I am a LPR and at the moment I have a couple of options to sponsor them. I am hoping I can get some input on which option would be best for me.

Option 1

My father or mother could apply for L1 visa. Both of them qualify for it but let’s say my father will. Once he gets his L1 visa, he will apply for green card. He could possibly get his green card within 1 year and sponsor my mother and sister to come to the US. My sister is 19.5 years old now and by the time my father gets his green card, she could be over 21 years old. To my understanding, my mother will be eligible for IR-1 visa and my sister will be eligible for F2B visa. The waiting time for my sister could be 9 years (1 year L1 visa + 1 year green card application + 7 years waiting on F2B visa).

Option 2

I become a USC and sponsor my sister. I just got my LPR this year, to my understanding I can’t apply for USC for 3 years. With this option, my sister will have to wait for 15 years to get her F4 visa (3 years of my USC waiting + 12 years waiting on F4 visa).

Do I understand the above correctly? Is there any other way to sponsor my sister faster than the above? My sister is a “special need”, she has a mental condition but she is physically well. Is this going to prevent her from getting green card? For example: Is she gonna be able to pass medical exam and interview process? My sister needs supervision and dependent to my parents because of her condition.

Any suggestions and feedback will be greatly appreciated. Thank you!

L2 seems more logical. She would age out at 21 so they would need to get going on PR.

You have it correct - assume you know it's the employer and not your father that will apply for L-1 and if he has company willing to sponsor, they can sponsor him directly for GC - L-1 isn't required at all. Your sister disability will not matter at all.

Company Lawyer will handle a L and sounds like timing is of the essence.

OP has not mentioned which EB classification and Country so the direct route to GC may not be practical.
