When applying for an Us visa, it is imperative to understand the different kinds of requirements that need to be fulfilled. You will need to provide certain information, like a valid passport, ESTA form, and proof of accommodation. Depending on your specific needs, you may need to present a friend’s address or print outs of hotel reservations. Alternatively, you can present proof of financial means, which proves that you have enough money to book a hotel in the U.S. upon arrival.
ESTA
ESTA is a program for granting travel authorization to eligible foreign nationals. If you are a Canadian citizen, you need this document to travel to the US. The ESTA application is only available online and must be completed at least 72 hours before your departure date. You will receive an approval response within 72 hours of applying, though a small percentage of your application may take up to 72 hours to process. You will need to hold a return ticket and an onward ticket or electronic tickets when you land in the United States.

An investor visa in the US allows foreign nationals to invest in American businesses and live in the country with their families. The investor must demonstrate that his/her investment has created at least ten full-time jobs in the US. The investor must also present a detailed business plan and show that he/she will keep the new employees for at least two years. The investor must also show proof of pending legal action in the US and civil documents. Investors can obtain a Green Card and permanent residency after two years of investment.
C-1/D visa
A C-1/D visa is required if the applicant is working as a crew member aboard a ship or airline. To qualify for a C-1/D visa, the applicant must have a letter from the employer confirming that they are working for the airline or ship. In addition, the C-1/D visa does not allow crew members to receive remuneration from U.S. companies. A crew member must also have a contract confirming their future employment on board of the vessel or airline. For these reasons, the applicant must have a permanent residence outside the U.S. or maintain a temporary residence outside of the country.
