I broke immigration law in the past when i overstayed in Japan and that affected my tourist visa application to the UK.. i applied for tourist visa twice to visit my fiancee and was rejected on both occasion.. we are getting married in november and we are planning to apply for a spouse visa after getting married..We are just concerned that my application will be rejected again..additional to these is we just had a baby.. Any advice on how we can guarantee visa approval ? Thank you very much..
