I am alloying for a spouse visa in feb 2014. I currently live with my husband overseas and work for a local company. I get paid a basic salary and monthly commissions which are sales based. I pay tax but get paid cash in hand. So my question is if pay slips a copy of my monthly commission ( receipts) and a letter from my employer is enough evidence. Also will I have to show 12 months incomings as my money varies month on month.
