Im a L1 Visa Holder. How long does it takes to my wife to get her a L2 Visa? Does she needs the EAD so she can work here?

Your wife must apply for a L-2 visa stamp at a U.S. Consulate if she is not lawfully in the U.S. in order to enter the country in L-2 status. Processing times depend on the specific post but should not be more than a couple of weeks. Your wife can apply for EAD once she entered the U.S. in L-2 status. It takes between to 60 and 90 days to receive a work permit upon filing of I-765.

Probably 3-60 days if you have your L-1 and she is in the home country. She will need to schedule an appt and prepare the form. Yes, she needs to file for an EAD once she has the L-2 if she wants to work.

The time it will take your wife to get an L-2 visa is mostly a function of how quickly she can get an interview at the American Embassy/Consulate nearest to her home. Generally speaking if the visa is approved, it is issued in 3 to 5 working days. She will not be eligible to work in the United States until she applies for and is issued an EAD.
