我兒子(和前夫所生)想來美國和我在一起,我要填什麽表格,做什麽手續,和準備什麽相關的資料呢?
-Depends on what purpose for his travel. If he just visits you temporarily, then he may apply for B-2 visa; if he wants to study in US, he may just apply for F-1 visa. If he wants to immigrate to US (i.e. get green card), then you may file I-130 for him to apply for the immigrant visa in China following the I-130 Instructions.
