回複:父母探親簽證的問題
Try to focus on the fact and don't lie. But try to find a reasonable way to explain. VO will understand that.
Since they have been here, it is good to have a good record, other than that, why still come since you back. Try to minimize it, but prepare a good explanation. Within several months, many things can happen, and if it is reasonable, I think VO will understand that.
Good Luck! Don't feel nervous now, at least try to help them practise or, keep on making better and better preparation
