If you are a foreign national and wish to visit Canada for a short period of time, you may need a visitor visa. A visitor visa is also known as a temporary resident visa (TRV) and it allows you to stay in Canada for up to 6 months.

To apply for a visitor visa, you must meet certain requirements such as having a valid passport, being in good health, and having enough money to support yourself during your stay in Canada. You may also need to provide additional documents such as a letter of invitation from someone in Canada, proof of ties to your home country, and a travel itinerary.

To apply for a visitor visa, you can submit an online application through the Government of Canada's website or in person at a Canadian visa application center in your home country. You will need to pay a fee and provide your biometric information (fingerprints and photographs) as part of the application process.

The processing time for a visitor visa can vary depending on the volume of applications received and the complexity of your case. It is recommended that you apply for a visitor visa well in advance of your planned travel dates to allow sufficient time for processing.

Once your visitor visa is approved, you can travel to Canada and present your passport and visa to the border services officer at the port of entry. The officer will ask you some questions to ensure that you meet the requirements for entry to Canada, such as the purpose of your visit and your ability to support yourself during your stay. If you are approved, you will be given permission to enter Canada as a visitor for up to 6 months.
