If you are an Italian citizen you can live in Italy whenever you like as long as you like, regardless of your other citizenships.
Yes, as long as you are not a defector.
If you hold German citizenship, whether dual or not, then there are no occupancy requirements.
You can apply for dual citizenship to the USA and almost any other country. Many more people than you might think hold dual citizenship. But the road to dual citizenship, with only a few exceptions, is long, twisting and full of "gotchas".
Since you have British citizenship, for an unlimited period of time.
Being already a Filipino citizen because of Dual Citizenship, You can stay as long as you like.
um ..... i am sorry i have no idea !!!
You can but as long as you have a permit to live in Italy. When applying for the permit, you should tell the Italian officials that you have two nationalities. Otherwise you'll get in trouble if you want to enter Italy on the passport they don't know of.
As long as said person has a citizenship in Mexico, they should be able to stay for as long as they want. However, it may be wise to get an identification card, but it shouldn't be needed.
Generally, as long as you want. Some counties (UK for example) allow citizenship to be revoked by the government unilaterally (i.e. they think you're a terrorist, and you have citizenship in another country. Cannot lose U.S. citizenship unless you revoke it, in person, outside the U.S. at an embassy.
It depends on the country and the situation. Some countries require that you give up one of your citizenships. Also, if you have citizenship of a country that requires you live (or at least return) for a set period of time (as in you visit at least once a year or live there for a certain number of years per number of years you live outside of the country) and you live outside of said country for too long, you may lose citizenship (note: some citizenships allow that you live outside of the country indefinitely).
As long as you are living in Canada and have citizenship you qualify for health care.
Viva Italia! (Long LIve Italy)
