Well, then you are NOT a Portuguese Citizen. You are an illegal and subjecrt to deportation, a tourist Visa is NOT a work visa, and it does expire. Doesn't matter if you pay taxes... without the proper paperwork... you are neither a legal resident nor a Citizen. You stated you applied but was rejected.

You would need a UK visa under these circumstances.
