How long does it take to convert from L1 to H4 and obtain H4 EAD?

I am currently working in L1 visa. To change employer i need a H4 visa and EAD (my spouse has approved I140). I need to know how long it takes for Change of Status - L1 to H4 and how long it takes to obtain the EAD card.

You can apply COS and EAD in parallel. The processing time is typically 2-4 months but you can check the exact timing on USCIS site for your processing center.

Thankyou!! The H4 visa timeline is given as 2.5 months and EAD timeline as 3 months. I assume these are the max period to obtain both.

Yes, but these timelines may change depending upon the load. But more or less it should be around this.
