常常看到有人问如何给父母办绿卡，首先就是要准备材料，我把要准备的材料列出来，希望对用得上的朋友有帮助。

- Form I-130, 本人 petitioning for father/mother, check attached

- Copy of Naturalization certificate of 本人

- Copy of 本人's passport

- Birth certificate of 本人

- Marriage certificate of father and mother (only needed in father's package)

- Copy of the court order for 本人's name change (if applicable)

- Form I-485, check attached, 2 photos attached (parent's) 

- G-325A Biographic Information (parent's)

- Form I-693, sealed Medical Examination Sheet (parent's) 

- Form I-864 Affidavit of Support (本人)

- Form I-864A (if husband/wife's financial support is needed)

- Form I-864 support docs: Tax return and 2 most recent pay stubs (本人)

- Form I-94 of father/mother

- father/mother's birth certificate

- Copy of father/mother's passport, including the page with nonimmigrant visa

如果需要申请Advanced Parole，用I-131表格 with additional 2 photos，因为费用已经包括在I-485的申请费里了，不申请也不省钱，所以建议一起申请。
