I got the I-797 (approval letter from the Department of Homeland Security) for my parents' immigration. Could you tell me what I need do next? My parents are in China now.
For my parents:
1. Which forms (G325A, DS-230 etc.?) they will receive from NVC?
2. Do they need fill I-485 in China?
For me:
1. Is I-864 the only form I need to fill?
2. Do I need send the copy of I-797 with I-864?
It is appreciated for your kind help.
