the same documents for parents.
my side,
bank statement,
mortgage statement
the letter to VO
employment verification letter for both me and my hu*****and
W-2
copy of passport and green card
my daughter's private school tuition statement
My aunt side
pictures(very important)
bank statement
her salary statement
certification of house
That's all.I would say it all depends on the VO. she had been rejected once before.
GOOD LUCK
