1) You don’t just automatically get residency because you’re married to an American. It is an extremely LONG process and it’s probably not going to work out well for you if you are in the country illegally, regardless of your marriage situation. For women who are illegal but mother children who are American citizens, citizenship or residency may come more easily… But even then, I wouldn’t hedge your best there.

2) You should share everything with your spouse. The attitude of “His” and “Hers” contributes to the idea that marriage (and subsequently, divorce) is just a negotiation of cohabitation. Marriage is so much more. It is a partnership and should be treated as such.

You think you are being wise, but you are not being very cognizant of humanity or reality.

-Be very careful when marrying someone that is an illegal immigrant. It can be very hard to know if they are with you because of love or the green card.
-Never co-sign a credit card/car with a lover or spouse.
-Avoiding mixing any finances or legal issues together.
