各位好, 都准备好材料了, 属于闪电般准备的. 所以在邮寄之前, 特别心虚, 总是害怕出错. 可是又懒得再查看一次, 太烦了. 突然发现一个问题, 说: Filing Fee : Although USCIS does not charge a fee for this form, the Department of State does charge a fee of $70 when the Affidavit of Support is reviewed domestically. This does not apply when the Affidavit of Support is filed abroad. 这是甚么意思, 864 到底需要附上支票不? 谢谢各位了
