Visiting the U.S. with a valid visa
Visitors who enter the US for other reasons than tourism or business for maximum ninety days, should contact the US Embassy in Brussels and obtain the proper entry visa sticker. These visitors will not be allowed in the US without the proper visa.
Visitors traveling with a passport that is not machine-readable also need to contact the US Embassy in Brussels and obtain a nonimmigrant visa.
Above visitors will receive a visa sticker in their Belgian passport. At check-in in the airport or during the flight, they will receive a white "I-94" card which the US immigration official will validate upon entry. The card will indicate the duration of stay allowed under that particular visa. Also in this case, the visitor should not overstay the duration of stay indicated. However, it may be possible to obtain an extension of stay while in the USA. Please contact the local Immigration and Naturalisation Office for details.
