Hi, I became a citizen last year and I want to apply for a green card for my sister, my sister has a tourist visa and she came to visit me a couple of times, I have a couple of questions actually 1- which is better to apply, CP, or adjustment of status? 2- if I applied through adjustment of status is it true that she can stay in the states until the process finishes even if her tourist visa expired? Appreciate it if anyone can help Thanks
