My parents are planning to visit USA,during the visa interview they told the intendent length of stay would be 15 days, I dont remember if it was there on the DS 160 .
But I am planning to make them stay around 4 months ,where I would be booking tickets onward and return .
Is it really necessary to have a return ticket ?
Can the return ticket be after four months.?
This is the first time they are coming down.
