Hey Vito! Me and my husband have been in the exact same situation!
He's American, I'm European, we had been going back & forth between Europe and the States to see each other, and well, this went on for two years, when customs started raising eyebrows at my third visit, we realized that this wouldn't work a fourth time. So we basically "rushed" into marriage. I know a lot of people think that marrying after having been together for two years is a pretty decent amount of time; but we weren't planning a wedding for at least 2 more years. So anyway, because of all the complicated paperwork, which I'm sure you know everything about; we just picked a day of the week, went to the court house and got married! I was wearing jeans, he was wearing an ugly a$$ shirt, and the whole thing was done in less than 20min

Not exactly my dream wedding.
BUT, I don't regret a thing, and nor does he. I knew I wanted to be with him forever, and he felt the same, so nothing else mattered. We first promised each other we would organize a really nice ceremony the next year for our first anniversary; with the white dress and everything. And as time passed, we sort of looked at each other and asked "Are you sure you want to go through all that stress when in fact we're already married?". And no, we didn't. So we said F?ck it. It's not how we had imagined our dream wedding, but so what? We're married, I feel just as married and committed as if I had had the white dress and all the superficiality that goes with it.
I don't understand your wife. Now you guys can live together, wasn't that the whole point? I can guarantee you, I've heard a lot of people saying that if they could do it all over again, they wouldn't organize a big wedding because it is so much stress and money.
I don't know, I feel kind of bad for you because she's being a little childish about it. Your situation was not "traditional" and you did what you had to do in order to be able to live together. I mean, it's not like you really had a choice; so why is she trying to blame you or even herself? Although I understand how important it is for a girl to have a nice wedding, as it's (hopefully) the only one you'll ever have

I think she needs to realize that not EVERYBODY marries with all the nice stuff, and that couples who don't do it the traditional way can last just as long, and even longer. She's creating her own worries and bad feelings, and I hope she'll realize that soon, and appreciate your relationship to its fullest. She could have been deported or you could have been deported, and then I can tell you she'd have quite something to worry about!!!
