多谢多谢8老师的详细解答!~ 还有一个问题:那I130交了之后I485大概什么时候交?
-About 10 years later.
是等移民局通知吗?
-Check the visa bulletin every month to see whether the priority date is current. If yes, file I-485. However, F4 category (US citizen sponsoring brother/sister) takes about 10 years for the PD to be current, so he needs to wait for a long time to file I-485.
还有他留学身份毕业后如果呆在美国,等排期的时候不是就黑了,那等排期到了对I485申请有影响吗?
-As I responded above, he needs to have his own status for about 10 years to file I-485. Otherwise, he may have to leave US and wait in China.
