Hi
All these days I was busy to prepare documents to submit a fresh applucation for Tier-2 General dependent.
We could prepare the following documents:
1- Printed 140 photos from three years ago, I and my wife together in different cities and ... (some with my parents and brother)
2- Chat records (Wechat, Chinese app) for last 8 months (since I changed my phone on January)
3- chat records and iMessage from three years ago but not continues (we changed our phones and some lost)
4- some photo from two month ago our tiny wedding ceremony in China with friends
5- Original tenancy agreement (with DPS) for a two bedroom property in UK.
6- A letter from agent on behalf of landlord showing the landlord agreeable to the main applicant's dependent moving into the property.
7- Council Tax Bill and utility bills showing my name and address
8- Original contract and a certificate of employee letter from University
9- Bank statement showing that the funds in the account have not fallen below £630 in the period of last 5 months.
10- A certificate of employment showing detail of my contract, starting date, salary and address.
11- An invitation letter signed by me taking the complete responsibility to support the dependant during her stay in the UK.
12-Original and certified translation of marriage certificate.
13- Copy of the flight tickets for the main applicant to travel to/within China for the marriage registration
14- copy of tickets shows I was in China for almost 21 months in last 3 years and I went to my wife's city a lot
15- All my offer letters from Chinese Universities and my Chinese visas (even I send my original previous passport) to show I was in China last 3 years
I hope we will be successful with these documents.
BUT, the big problem is a letter from employer that tells they will support my dependent first month, which I saw everyone submitted!! (my sponsor is a big University and A-rated and I can't understand why we need this letter when I have salary here and I showed my saving).
The problem is, my Uni doesn't mention my wife's name in their letter and they have only one format from HR services. They said it's not their position to prove my marriage or my wife's name, and it's HO responsibility to decide is she my wife!? (which makes sense) they are my sponsor and they said my salary is enough to support my family. They said everyday 10s Chinese and other nations bring their wife to UK with the same letter !!!
Guys, what should I do? Should we apply with those documents I mentioned before without the damn letter showing my wife's name? or again they will reject me? How can I solve this problem? who can give me that letter?

as I mentioned before, Uni doesn't have any other format of letters!
Thanks
