If you are an American and you date a foreigner, you can invite your date to visit the US with the help of a K-1 visa – which allows the noncitizen to live in the USA for 90 days. You must wed during this period or the noncitizen must leave the country after 90 days. Some other countries also have possibilities for a fiance visa but with little bit different conditions. To get such a visa for your date you should prove you do have romantic relationships with the noncitizen, show photos from your meetings, and impress officers in the Embassy with your excellent knowledge of habits, dreams, and features of each other. If you get acquainted with the help of an international dating site that abides by the rules of the International Marriage Broker Regulation Act (IMBRA), this will be easier to prove your sincere intentions to the embassy officers.
