Tier 2 dependent visa funds maintenance

Hi

need some quick help , i am planning to apply for Tier 2 Dependent visa for my wife and she is having slot in next week in Bangalore VFS on 27th Apr.

I have sent all required documents and still i am worrying on Maintenance part .

Though i am getting salary of GBP of 2125 per month as a take home salary but due to some personal maintenance i used to send amount to India and i used to withdraw the amount here as soon as i get a salary here for my rent , and other expenses .

So i dont maintain the minimum amount in last 90 days as i was told by some one saying that if we can get the letter from Employer for evidence of Maintenance then no need to submit the bank statements .


I got a letter from my employer saying he can support my wife for 1st month and here is what he has given me on 23rd Mar on original letter head and with office seal.
