Try telling an immigration officer your intent was to get married while on a tourist visa and applying for a change of status to gain residency and see how far that gets you.Then the logic behind the change of status using the 485 form is not a legal method? This scenarios are contemplated on the USCIS process, if there was intent or not is not questionable as long as you follow the rules. Hey, we all do things that were not our original intent, and sometimes we do it knowing the consequences.
You may not LIKE the laws, but they are in place for a reason.
Many, many---ourselves included---have gone through the system, looking for short cuts, only to understand that what appear to be shortcuts are fraudulent actions.
Honest Dominicans suffer because so many Dominicans have gamed the system.
It doesn't take a lawyer to understand that.
