My visa application to visit my father in the UK has been refused because I said that I will stay in the UK for 60 days while I'm a student in my country. They said that I didn't provide any document that explains why I'm going to be absent for 2 months while I'm a student, plus I didn't provide any documents that shows that I can support my self financially here.
Should I wait to reapply and can I change the period of 2 months in a new application?
