Fulfilling the requirements for U.S. citizenship does NOT cancel your Canadian citizenship. Canadian citizenship is permanent, and (unless obtained by fraud) cannot be revoked by the Canadian Government for ANY reason unless you renounce it yourself. Also, the U.S. does not require Canadians to renounce their citizenship when becoming U.S. Citizens.
Americans can live in Canada if they apply for permanent residence. They do not, however, need to "give up" their citizenship and may apply for a dual citizenship. They will have both a Canadian and their American citizenships.
People buy business or any property in other countries without citizenship like Shahrukh khan because they have a visa to stay in and do business in that country.
No, because Eu citizenship is a consequence of Member State citizenship and it cannot exists independently. Eu passports are actually Member State passports that follow a common format: they are issued by the Member State, not by the European Union. You can obtain however residency and citizenship in a EU member state through investment. Some member states such as Bulgaria allow you to obtain a Bulgarian Citizenship without physically living in the country but you have to meet certain criteria.
Many countries will allow you to have dual citizenship. However, the US does not grant that privilege. Unfortunately, under U.S. law, one can not become a citizen of another country without losing their American citizenship. If you become a citizen of Australia, you will then no longer be a U.S. citizen.
That limits it, by a lot. Without citizenship you can get jobs that are not legally jobs. As is petsitting, babysitting, etc.
If you are born in the UK and have a British Passport with status as British Citizen (British Subject is different), you can stay out of the UK for as long as you like without losing your nationality, unless of course, you have applied for nationality of another country. Even then, you may still be entitled to dual nationality.
It depends on your citizenship.
lots of paper work
If the immigrant is a true illegal (i.e. entered the country illegally/without inspection) even a marriage to a US citizen wont prevent him from facing possible deportation. Moreover, an immigrant CANNOT apply for citizenship, they must first apply for legal residency
No! There is no requirement that you speak English to be legally in this country. It is possible to get visa's for all sorts of purposes in order to legally reside in this country. In addition, you can get legal resident status and a green card without being able to speak much English. It is a bit more difficult to become a citizen without speaking English but it is possible knowing only small amounts of English to get through the citizenship test and other requirements for citizenship.
Absolutely, without proof of citizenship the insurance company won't entertain. Since citizenship is the true identity.
Yes. It is possible for a UK citizen to buy property and live in the other countries of Europe such as Spain without visa and permit.
