you are naive and a normie. i would encourage you to see more of the united states and to explore how little you actually need to live; you should also visit the third world, with or without your gold-digging visa-seeker. why are you hiding this girl from your parents if you plan to marry and integrate your families? do her parents know about you?  > of course she wants to live here even though i have told her countless times that her country is better. which country? if it takes a year for her to get a tourist visa and visit you it's almost definitely not better than the united states.
United States
