Tier1 general help

[skumar123a]

Hi Everyone,
This is my first post . Good to see people helping us here.
Ok I will start...
I am applying for Tier-I General Extension in Person in Sheffield PEO.
These are the Documents I am taking with me
1. Passport wth 2 recent Photographs.
2. Application with Covering Letter.
3. My 12 months bank statements.
4. Payslips and employer letter.
5. 3 months maintenance funds bank statements.
6. My qualification proof.
7. As I have already proven my English language requirement, I am taking any prove my English requirement.

My questions (Hope the above documents are sufficient):
1. My company sends me a soft copy of the payslip which has my company logo on it. So I colour printed all my payslips.
2. I got a letter from my employer. This letter has my Job title, Job status, Job start date and my pay details (i.e. 46k per annum). My HR just mentioned my salary as - 48000 per annum as of today - in the letter. It would be embarassing for me to ask her to change the letter. I will be taking printed payslips, bank statements and my employer letter as my Pay proof. Will this be alright or should I ask my HR to change the letter.
The reason for asking is in my intial Tier-I General application my employer letter did not have the individual monthly pay details (only per annum salary details).

Please help me on this as this is the only doubt I have about the documents.

And please let me know what kind of questions to expect from the Case Worker at the PEO office.

Thanks Guys
