Hi, Currently i am on L1 and my wife on L2. I am applying for H1 this year. So i need to submit the I-539 form for my wife. What option i need to select "Application Type" in Part-2 ? What option i need to select for "Change of status i am requesting for"?
I-539--> Part 2---> 2b Change of Status i am requesting for?
