A minor in the US needs parental permission to marry. Even if the parents of the minor allowed her to marry and she would then be considered emancipated it is unlikely she would be able to apply for a spousal visa for her husband until she is of legal age. If the minor marries outside the US the marriage would be legal. A minor cannot legally leave the US without parental permission and in most cases being accompanied by an adult. A minor who left the US by illegal means and married in a foreign country would not be considered legally married in the US.
No. But only if the person already has US permanent residency.
The prisoner would need to obtain permission to marry and it would be highly unlikely that such permission would be granted. If allowed, marriage to a US citizen would not prevent the foreign national from being deported once he has served the imposed sentence.
Yes, an NRI or Foreign National can be a Partner after obtaining a DPIN. At least, one of the partners has to be a resident Indian citizen.
No, she will not lose her nationality. Chances are she may also get foreign national's country citizenship too. However, marrying a foreigner does not have chances of losing nationality.
Citizen and national are terms that are often used interchangeably. In some situations a national might be considered as someone who originally came from another country or is of a different race to most Irish people. This would be particularly where the term "Foreign national " is used. They could still become a citizen of Ireland, as many have.
Yes. The foreign national would not yet be eligible to apply for permanent residency therefore divorcing his or her current spouse and remarrying would not affect his or her status. Be advised, that it may create difficulty when the application for permanent residency is made.
Yes
To the US government and people, they would be a foreign national. If they reside in the US, they're considered a 'resident alien'. If their residence in the US isn't done properly, then they're illegal aliens.
If you have a green card, or can show proof that you have applied for a green card, you may enlist in the US Army as a foreign national.
Yes, marriage by a foreign national to a US citizen does not automatically confer US citizenship upon that person.
That depends on whether the foreigner actually was actually a spouse, or just a holder of a spouse visa (green card).
That depends upon how successful you are, and whether you're a citizen or a foreign national. If you're a citizen and you fail, you could be charged with treason and imprisoned for life or executed. If you're a foreign national, you would receive a life sentence or the death penalty on other charges. If you succeed, you would probably create anarchy and screw up what's left of the economy, among other things.
