I want to invite my parents to US. Should they submit one application form or two? I do want them to come here together. Should they pay for one visa fee or two?
Also, I want them to try to get the visa at the beginning of Feb. and then come here at the end of April, when should they make the call to set up the interview appointment? They will do it in Beijing.
My hu*****and is Citizen and I am a GC holder, what kind of material should we prepare for my parents?
This is the first time I am inviting my parents here and I am so confused. Any help is highly appreciated.
