My retired parents returned back home in JAN07 after spending 6 months with us on a Visitor Visa. Now they want to visit us again in Summer. Will there be an issue with it or is there any rule that they can apply for a visitor visa after a certain time period???
no issue as long as they returned back within their legal timeperiod of staying in UK. My mother has fiver yer multiple entry visa and she does that quiet a few times.
