You will require a Resident Permit or a letter from your employer stating your resident permit is in progress and a likely timescale.

If you want to apply for a bank loan or CC, you will require a salary certificate or letter from your employer stating how you are compensated. For Example, Salary, Housing Allowance, Utilities Allowance etc.

The Bank will also require you to pay your monthly salary into that account when you draw a loan or CC and your employer should state that if you situation changes, they will notify the Bank immed.

 

Good luck.
