You can’t just show up somewhere and be given citizenship. It doesn’t work like that. The best you can expect, and that is if you get a job or have enough money to start a business in that country assuming they take that sort of application is residency and sometimes not Permanent Residency but the type that needs renewing
Usually applications are made on the following grounds:
Asylum seeker (strict guidelines and quotas even)
Family Reunification
Temporary Work Residency given for the term of the work contract
Temporary Study Residency given for the time of the study position which has to be approved before residency will be given)
Business Investment (you bring over boat loads of money and start up a business that offers employment to local people)
In most cases, you will be given Residency, NOT citizenship. Most countries require a certain number of years of residency before you can even apply for citizenship. If you work, you may be taxed and given no right to vote in their federal elections. (Like I have for the last 7 years where I live) If you have children or a spouse, they may not be granted residency just because you have. I have watched as visiting professors kissed their children and spouses goodbye at the airport after having them here for 3 years when their final application is rejected.
Oh, and again… remember those grey countries, otherwise you’ll have mandatory health care jammed down your throat. The Baltic States are pretty, but they still have a bit of unrest occasionally.
Oh.. and be prepared to learn at LEAST two new language….
Go’ bedring….håper du er aldri syke.
