That's because New York gets forwarded to more complicated/red flag applications. Normal US applications are actually processed through Ottawa.
As for the original post, I'm sort of at a loss. I'm trying very hard to understand, but there is no way you can win. There is no easy way out. You don't want to step on any toes, and you don't want to be at fault, but you don't want to sacrifice your happiness. You cannot have all three.
I suggest you put your happiness before the anger of your parents.
There is no way to get out of this without people getting upset, but I urge you to muster up all your strength and courage, and put yourself FIRST. YOU are the most important person in your life, don't make yourself a martyr at the pressure of others, do not sacrifice your happiness.
Refuse to file the paperwork. Stop talking to them. He may file for divorce on his own accord. If he doesn't, you can get a lawyer and file for divorce yourself.
I'm sending you all my strength, you need it. Be tough.
There is NO way to end this without your parents getting upset. There is no way to end this without stepping on any toes. CIC isn't gonna solve your predicament for you. Sorry, but there is no easy way out. People are going to be upset, regardless. End it.
If you want to be happy, I urge you to take the initiative and deal with the "blame", and break up with your parents and your husband.
You deserve to be happy, even if your parents are mad at you because of it. If they care about you, they will want you to be happy, too. They might not realize that right now, but they will some day.
Muster up all your courage, your strength, tell them you are not filing for PR. TELL them that you're not, that you do not want to be in this marriage and there's nothing they can do about it. If it's easier for you, you could ignore them and stop talking to them completely. I would not let them harass me or bogart me into sponsoring someone I don't want to be with. They are in a different country from you! You're safe. I know it's not "IDEAL" but there is no "IDEAL" outcome for this situation.
Hang in there, okay? And do what is right. Take responsibility for your life, it's in your hands and yours alone. Trying to get CIC to break up with your spouse and your parents will only make things worse for you in the long run.
