I have just discovered that the 14 year rule changed last year and i am now in a panic about what to do! I have completed 14 years in Nov 2012 ( 5 years on student visa + 9 years overstay) and was planning to send my application this month. Is there any chance they would still accept it?

I am a Croatian national and as you may know Croatia will join the EU on the 1. July this year. Is this going to change my situation in any way?
Hope someone can help!
