Canada - 10 January 2022: 

The US Centers for Disease Control and Prevention has placed Canada in the highest-risk category for travel.

As the Omicron variety spreads, Canada, the world's second-largest country by total area, has experienced a sharp increase in instances. According to data from Johns Hopkins University, the country saw 294,437 new cases in the week ending January 8, the highest weekly total of the pandemic.

When more than 500 cases per 100,000 population have been registered in the previous 28 days, the CDC assigns a destination to Level 4. Travelers should avoid Level 4 countries, according to the CDC. Previously, Canada has been at Level 3 since August 30, 2021. Most international visitors to Canada must be completely vaccinated and have a COVID-19 test result of negative.

U.S. - 4 January 2022: 

If you are a non-U.S. citizen or non-U.S. immigrant, you must be fully vaccinated before flying to the United States (not a U.S. citizen, U.S. national, lawful permanent resident, or traveling to the United States on an immigrant visa). There are a few exceptions.

When flying to the United States, you must have a negative COVID-19 test result or confirmation of recovery from COVID-19. You are considered fully vaccinated:

• 2 weeks (14 days) after your dose of an accepted single-dose vaccine
• 2 weeks (14 days) after your second dose of an accepted 2-dose series
• 2 weeks (14 days) after you received the full series of an accepted COVID-19 vaccine (not placebo) in a clinical trial
• 2 weeks (14 days) after you received 2 doses of any “mix-and-match” combination of accepted COVID-19 vaccines administered at least 17 days apart

If you don’t meet these requirements, you are NOT considered fully vaccinated. 

Australia - 20 January 2022:

International students applying to study in Australia will no longer have to pay a AU$630 visa application cost for the next eight weeks.

“We will be rebating the visa application fees from all those who arrive today and going forward for students over the next eight weeks and that is a fee of some $630," Mr Morrison said. “There are around 150,000 students who have visas who we are encouraging to come back to be there for the start of their university or college year and that is a thank you to them for coming back and continuing to choose Australia.”
