In this case you should file Form I-601 in order to seek a waiver of certain grounds of inadmissibility.If you care able to support your case with enough evidences and proof you may get a waiver and US citizen can petition if your case is cleared.Such cases legal help may be more helpful.
I think it is a federal crime to offer services to an illegal alien, not sure if that bill passed or not...
NONE. Marriage to a US citizen does not in any way automatically confer any change in immigration status. Your US Citizen spouse can now petition to have your immigration status changed, but you will almost certainly have to leave the country and return to your home country to pick up the new visa, and, depending on the case, you may NOT be allowed to return to the US for up to 10 years.
If by "alien," you mean an illegal alien, and not a creature from outer space, being a 69 year old senior and having a home do not generally exempt him. He would need proper papers, or to become a citizen in order to stay in the country legally and not risk being deported.
NO,UNLESS HE IS FROM MARS.
Not without becoming a legal alien. Which usually requires returning to their home country and applying for a marriage visa.
well they would have to be adopted or the friend would have to be a foster home
Any US citizen no matter if they are in the armed services may marry whoever wherever. Marrying an already illegal alien does come with a few complications. For one, INS must by policy view it as fraud. (according to INS policy) It is the US soldier and illegal aliens responsibility to prove it otherwise. If the petition is accepted after being filed that illegal must return to their home country to await a perm. residency interview at the local US Embassy. As well as possibly pay fines for being here illegally in the first place. If the interview goes well they will get a visa to enter the US on a perm. residency based on marriage to a US citizen. (I assume if they are a US soldier) If the US soldier is NOT a citizen the wait time is much much longer and the possibility for denial goes up higher.
Marriage is recognized by the US , but they must report it when they get home. It does not affect their alien status.
Return to their home country and apply for a visa.
No, but you would expose their illegal status.They would have to go back to their home country and you'd have to file for a fiance visa to bring them legally to the US, after that you'd have to get married here and file for a I-130 (Petition for Alien Relative) I-485 (Adjustment of Status) and I-765 (Employment Authorization Card).www.uscis.gov
Sometimes. The immigrant must follow the same procedures and apply for the green card. Often, they must voluntarily return to their home country to wait for their visa and permission to come through.
No................. The only way they can become a US citizen would be to go back to their home country and then apply for a fiance visa, and then you have to go through all kinds of forms to make it happen. It is pretty well cut and dried here, once an illegal, always an illegal, unless you go through the proper channels. Go to USCIS.gov
