Hello,
This case is a bit complex. My brother lives in Canada with a student visa and valid US b1-B2 visa. My Parents are recently coming to USA as their interview date is in November. They will be on IR-1 visa and will have LPR once they come.
Now, the complex situation is that my brother is under 21 and will be 21 next year in January. But, will remain unmarried. He wants to come to USA and stay, what are the options for him to stay? and, also potentially work or study?
Have my parents submit both I-130 and I-485 at same time? Also, with that submission, can he drive/work/study?
Thanks for the help!
