Adhing,
You did not respond to my questions in your own thread.
Your situation is somewhat complex in that UKBA does not normally issue Family Permit for Fiancee as that is not recognised as family members or extended family members in the EEA Regulations unless you can show durable relationship (generally means co-habiting)
However UKBA do have special case approach for fiancee of EEA nationals under paragraph 290 of the UK Immigration Rules.
Generally this involves applying under UK Rules and paying the needed visa fee.
Now, under paragraph 290 of the UK Immigration Rules, an EEA national who is a qualified person in the UK is considered as present and settled if they have permanent residence.
This means you have most probably been assessed under the Immigration Rules and not the EEA Regulations.
Without full knowledge of your current status no-one can give you any meaningful advice.
If my guess is correct then your best option is to contact UKBA and have them inform you of your status here in UK and what next steps you must take to remain here legally.
Sorry to Gretta for off-topic posting
