Covid Delta variants surge, the Biden administration has adopted numerous travel restrictions curtailing international trips to the US.
The United States has restricted travel from the European Union, Britain, China, and Iran for more than a year due to the Covid-19 pandemic, later adding other countries including Brazil and India.
All travelers to the US, regardless of vaccination status, are required to show proof of a negative Covid-19 test taken within three days of air travel to the country.
Currently, the only foreign travellers allowed to cross by land into the US from Mexico and Canada are essential workers such as truck drivers or nurses.
