I am applying for my wife’s sister, her husband and 2 kids (10 and 7). Husband applied once alone in 2018 and got rejected. We weren’t involved then. Should we apply through old or new portal for success and quicker response? We have all their docs as in employer letters confirming jobs and no objection to travel during holidays and letters from kids schools of admission and enrolment, and their properties documents, bank statements, marriage certificates, passports, husband has Schengen visa and has history Of travel via his job related travels.
can I buy air tickets also to show ?
