If there are changes made that affect the application and conditions of FLR, ILR or Naturalisation and those changes are effective before you make an application then they will impact you.
Yes but what I mean is that so long as the rule changes are not made retrospectively then in my situation I wont be effected, and my situation is that my FIance Applied for a Fiance Visa a few days ago, UNDER the OLD RULES, so once we are married and apply for the FLR we will still be under the old rules, so long as the rule changes are not made retrospectively correct?
