Of course, there are no laws in the forbidding a legal resident from traveling to another state or all over the country. That is assuming that there have been no restrictions applied by a court or the Immigration department.
It depends on the state you reside.
Unless you have some legal document that forbids you to remove your children, travel between states in the US is not regulated. You are free to travel as you wish.
It depends if said alien is from Space or your more garden variety location, such as Mexico.
The law is different from state to state. I would advise checking your local DMV for what is and is not legal in your state.
Yes.
Yes. Or, rather, I should say that the fact that one is a resident alien will not prevent him or her from marrying the other one. No state in the US limits marriage to only citizens. It is even possible for a US citizen to marry a undocumented alien in the United States. There is no residency or citizenship requirement to marry in the US. The only thing that could prevent you from marrying is: if you live in a state where same-sex marriage is not legal (you can travel to another state if this is the case); if one or both of you is already married to someone else (you'll have to get a divorce first); or, if you are closely related to each other by blood (the degree of consanguinity that is prohibited varies by state).
As regards to what? Custody? Child support? Travel expenses? When you ask a legal question, it's very helpful if you provide as many pertinent details as possible including the state(s) and/or country involved.
If you mean a legal resident alien, yes. If you mean a legal resident of Arizona, yes. If you mean a legal resident of another state- THAT depends on which gun. You may purchase a rifle or shotgun from a dealer in any state (unless you reside in CA) but you may only purchase a handgun in your home state.
Yes, as well as being a FEDERAL CRIME, it is immoral and destructive to the country. The legal alien also risks revocation of their legal status and deportation. If the illegal doesn't care enough to do things legally, who the heck wants them here? What kind of citizen (other than selfish, greedy and irresponsible) will they be?
An alien has three eyes and it really depends whether what state the alien is in.
If the marriage license was issued and executed, the marriage is going to be considered legal. It could be annulled, depending on the laws of the state in question.
As long as your registration is up to date you can travel into any state and be legal. There are no laws that say you can not cross state lines.
