Hi everyone,

I have an emergecy question!
Do you know how long after being rejected for a visitor visa i can reapply?
I have heard 6 Months!!! is that true?
My mom's application was rejected 2 months ago and she is going to apply again. at this time she has more education and the reason of her visit has changed!
I'm looking forward for your answer,
Thanks,

You can re-apply at any time. You don't have to wait six months.
