illegal immigrants who have been living in Spain since August,2004
for Residence Permit. But it's conditional residence permit. And you
can not work in UK with Spanish Residence Permit because UK is
not a Schengen State.

To get visa for Finalnd is very hard as an Iranian citizen so you try to select different country in Europe.
