Bank statement....please advice..

[ra_one_2011]

hello there,
i am going for my ILR application soon and want to know..
i got a bank statement from my bank which are on their own stationary but it shows only date when they were issued/ generated in their software system. i.e. january 2011 statement says isssue date March 2011 and so on. Is there any rule that these statement has to be within last month? please reply soon.
thanks in advance.

What route are you taking...If tier 2 then they normally ask for last three months statement...its not the date generated its about which months it covers, for example if applying in may then you need statement covering april, march and feb period to show income during the last three months
