I'm a UK citizen living in another EU county. Here we are called immigrants or worse, aliens.
It costs 20EUR to get register with the migration dept and has to be done within 90 days of arrival.
They want proof of income, housing and want to see that a person won't be a drain in the state.
People under retirement age who are not working must have fully comprehensive medical insurance.
After 5 years the initial registration can be changed to permanent residency, also costing 20EUR.
For this they want proof of 5 years legal residency, so 5 years of a utility bill, 5 years of rental agreements or 5 years of bank statements.
Nothing is done online or by app. We have to physically go to immigration in our district and make an appointment. They provide a list of what to take back at the appointment which could be anything from 3 weeks to 6 months in the future.
Would be chuffed to have an app.
As it is now, we have to smile through gritted teeth while our lives and finances are picked over by a bad mannered civil servant who would not even get an interview for a similar job in UK.
