请问能否申请儿子到美上学?
-How old is your child? Your child may be difficult to get the F1 visa because you are the green card holder and the visa officer may think your child has the immigration intent.
How did you get the green card, employment based or other ways?
You may sponsor your child's immigration visa (green card). If your green card was obtained by employment based category, you just file I-824 and your son can do follow-to-join to get the immigration visa in 6 months to one year. But you used family based category to sponsor your son immigration visa, it may take 3 more years for him to get the immigration visa.
Your divorce does not affect your son to get the immigration visa.
大概要多长时间?怎样申请?谢谢!
