the question is Now my father wants to file a case for my settlement what docs are needed?
1) For a company director? i.e does he needs the payslip or would he send the business invoices instead?
2) "HOW TO PROVE THAT I AM HIS DEPENDENT".
3)would my UK immigration history be a problem i.e would Irish authorities check the previous immigration history?
