回复：请教8大师，P大师和各位大侠, 亲属移民问题

My sister and her families get approval(green card), but my brother-in-law doesn't want  to quit his current job, come to US at this time.

My questions are:

1. If he gives up green card, and doesn't come with my sister to US now. Does he have chance to come to US later (like vistiing my sister and his child)?

- He is not considered to have a green card unless he enters using this immigration visa before the vis expires. If he does not enter US before the immgration visa expires, this visa will be void. So, if he wants to get the immigration visa again in the future, his wife may just file I-824 for him to apply for the immigration visa again in the US Consulate in Guangzhou. Of course, he may apply for the B2 visa to visit his wife, but he needs to show the evidence that he give up the immigration visa and have no immigration intent during the B2 visa application.

2. If not, when his child has US citenzenship ( 6 years later), can his child still apply green card for him ?  Will immigration won't approve his case since he gives up it before?

Thanks you very much!!!
