父母在国内， 我现在这边递交申请，问题：
1. 俩人一起递交，还是分开递交？
-Do you mean you sponsor your parents to apply for the immigrant vis in China? If yes, you need to file two I-130s, respectively, for your father and mother. Then, wait for USCIS aprpoval of the I-130s. Then, USCVIS will forward the approved I-130 to National Visa Center (NVC) to process for the immigrant visa application. NVC will contact you and send you the instructions at that time, then you just follow the NVC instructions to provide what they ask. That is all.
Read thsi website for the basic porcess:

2. 我明白第一步是 i-130, 可看网上写还需 i-864, G-325A. 这些是和 i-130 一起交吗？-No. Only need to file I-130 following the I-130 Intructions.
之所以这么问，是在uscis网上没看见。
