Tier 1 - Dependent - Queries

Guys,
I have couple of question regarding documention which needs to be included / submitted. I want to be doubly sure and make sure that i have included everything as this is my second application. First one rejected because of maintenance fund.

- Firstly, Do i need a letter from bank (HSBC) stating i have required maintenace fund held for three month in my account or bank statements would do (last three months). These are monthly statment posted by bank.

If i do need a letter, any idea if HSBC would be willing to give that letter?

- Secondly, Do i need NOC letter for accomodation proof. I have rental agreement signed in 2008 + council tax letter showing yearly payment till date + phone bill + credit card bill showing home address.

Thanks
D
