How to Get Citizenship in US?

Yes, Puerto Ricans are US citizens. Google "If you marry a U.S. citizen, do you become a U.S. citizen?" and you'll get a bunch of answers. Apparently if you do it right, you get a green card and become a permanent resident, but have to apply for citizaenship and pass the test. Remember there were a lot of cases of sham marriages and paid marriages just for the purpose of getting a green card, so Immigration checks up pretty thoroughly, I'm told. You have to do things like live together, for starters.

Basically there arent' any easy ways to become a US citizen. For better or worse, they're pretty tough. If you do that google, you';ll probably get a link to a paid site that says they have immigration lawyers standing by to answer your questions--apparently you pay per question. Don't know anything more about it than that, but a lawyer is more likely to give you a complete answer than we are, or than you will get at a web site.

There are only two ways to become a U.S. citizen: either by law, or by birth.
naturalization, an administrative process that requires you to take some action and which is strictly governed by the Immigration and Nationality Act (INA).
Generally -- very generally -- you may not be naturalized unless you:

1. Are at least 18 years old and a lawful permanent resident ("green card" holder);
2. Have resided continuously in the United States, having been lawfully admitted for permanent residence, for five years immediately preceding the date you filed your application for naturalization, or
3. Have, after having been removed from conditional permanent resident status, based upon your marriage to a U.S. citizen, having resided in the United States for one year after the date the condition was removed;
4. Have resided continuously in the United States at all times after your application to the time and date of your admission for citizenship;
5. Have, during all periods of time referred to above, been and still are a person of good moral character;
6. Have no outstanding deportation or removal order and no pending deportation or removal proceeding;
7. Have the ability to read, write, speak, and understand simple words and phrases in English;
8. Have knowledge and understanding of the fundamentals of U.S. history and government;
9. Are attached to, and can support, the principles of the U.S. Constitution and can swear allegiance to the United States.

In addition to marrying a U.S. citizen and receiving the "green card (GC)" , you need to be married for 2 years in order to have your GC extended. If you don't
pass the 2 year mark and do not ask for an extension yourself, your GC will
automatically be cancelled.

If you marry an American and the two of you live outside of USA you cannot get a US Citizenship no matter how long you are married.

Just how thorough are the authorities checking the sham marriages and allowing foreigners to become citizens. There are couples who just live on together as friends until the spouse has got their citizenship. Believe me I know one such couple.

One of them has a friendly spouse then..
