父亲有绿卡。现为继母办绿卡。有I-130 approval. 请问 Form I-485 中Part 2 应选A还是B？
A[ ] An immigrant petition giving me an immediately available immigrant visa number that has been approved.
B[ ] My spouse or parent applied for adjustment of status or was granted lawful permanent residence in an immigrant visa category that allows derivatives status for spouse and children.
谢谢
