Foreign travelers to the United States and Niagara Falls USA for short visits such as vacation or holiday, must first obtain a visitor visa, unless qualified for entry under the Visa Waiver Program.
There are several steps required to apply for a visa and they may vary at the U.S. Embassy or Consulate where you apply.
