No. A passport is absolutely required.
No.
You are able to. I was a permanent resident with a green card( actually pink) and i went to Mexico and Canada with it.
Yes, provided you have an American passport.
To fly into Mexico you HAVE to have a passport. As of right now the only way you can get into Mexico without a passport is by land travel, but that will change as of Summer 2009. As of Summer 2009 you will need a passport for any land travel into Mexico and Canada.
If you are a permanent resident with a "Green Card" then you can leave and enter the US at any time. Check out passport requirements though. Travel documents requirements have changed in the last couple of years.
I guess you mean "passport". No, without a valid passport you cannot leave Mexico.
Yes. All you need is a valid passport.
Yes you can apply for a temporary resident visa card in Mexico if your son is Mexican. Among the stated requirements is that you can prove you are related to a Mexcan, or to a temporary or permanent resident of Mexico.
Green card holder can travel within US states.As a U. S permanent resident you do not need a visa to visit Mexico. At the border or on the airplane you can get a tourist card good for up to 180 days. If you are going to FLY to Mexico you DO need a passport. You must use your passport from your home country since you cannot get an American passport until you become an American citizen.
Absolutely. Even if they are legal Resident Aliens.And I belive they need a passport issued by Mexico, and should keep one current as Permanent Resident Aliens, they are still Mexican Nationals.
To Canada you can; to Mexico you can't.
If you have a European/Italian passport, you can enter Mexico without many issues.
