Similar situation to mine. My husband didn't even stick around for the paperwork.
Its true your baby will be a US citizen but that is useless information for your current situation.
People who do not understand will always ask did you try and get a
green card etc like we
didn't think of that!
Lawyers charge loads and
don't even really help in this matter. Pay a fee for a consultation only just to get an idea then do as the Mexicans do cos they ought to know. Go to your catholic church who has an immigration section and they will be direct and honest of what you can do.
Other than that it is my experience that its a no win situation. We are screwed if we stay and
screwed if we leave. Obviously you want to stay otherwise you would have gone home.
Get in touch also with a
woman's protection society, there is a lot of red tape mind, you have to have lived together for them to take you seriously, married or not.
I'm up shits creek cause my husband and I lived in a hotel so I cannot get any help for the domestic violence he subjected me to, but you are pregnant and im pretty sure that elevates the dynamics here.
Let me know. Perhaps we can help each other. Read my crappy situation under "Can I marry, stay, or divorce-----or something like that!
