Student Tier 4 applications - maintenance funds must be in bank accounts for at least 28 days.

From 1 October 2009, for all points-based system Tier 4 applications made outside the UK, the amounts required to meet the maintenance criteria must be held in your personal or your parent(s)/ legal guardian(s) bank account for a minimum period of 28 days prior to making your visa application. The end of the 28 day period must not be more than 1 month before the date of your application, for which you must show bank statements/other evidence. The transitional arrangements that were in place allowing funds to be held on the date of application only will no longer apply to applications made outside the UK, on or after 1 October 2009.
