This is how it works here. I will absolutly provide you with the proof now. It is exactly what happened. Are you going to be able to help me? Or is this all just for kicks??
Okay. Here's the bottom line.
CS is ordered - and actually sounds in line with guidelines now. No going back there unless there's a change.
Spousal support (for whatever reason - it sounds like she got savvy and knew a little bit more about potential sponsorship than you did) is ordered - and if you want to get that changed at this point you're going to have to have a reason to modify the order. You also need to read your decree to see if it IS actually modifiable.
I'd like you to clarify, if you can, her immigration status.
You said first that she was here illegally. How? Did she enter on a tourist visa and overstay? WHEN did she enter?
You never filed anything on her behalf, correct? Not one single form?
Yet she's now a citizen? Are you absolutely SURE about that? Because if she wasn't even a resident as of 2007 when you got divorced, the timing just doesn't work.
