1. 如果境外申請，130 批準轉到NVC後最長可以隔多久必須交下一步的材料，
- Case by case. NVC will contact you for the documents and fee and send you instruction.
也就是說130多久會失效？
-Your parents need to file DS 260 immigrant visa application within one year from the date NVC send you the instruction for the documents and fee.
2. 130 批準後是發信還是email給我，還是父母？
-USCIS will mail the I-130 Approval Notice to you.
NVC的通知是發信還是email？給我還是父母？
-NVC will email you, not your parents.
我在填表時能把mailing address填我的美國地址嗎，
-Yes, you can use your address as your parents's mail address. In the I-130, you need to put your parents' address in China as their "Beneficiary's Physical Address" in Part 4, Item 11.c. to 11.h.; and you can put your address in "Other Address and Contact Information" in Part 4, Item 12.a. to 14..
還是必須要境外地址如果他們是境外申請？
3.無犯罪記錄公證是不是最早在交材料前半年辦，也就是半年有效?
-It needs to be less than 6 months, so you had better not do it until you get the NVC instruction or get the interview appoinment notice.
