The Trump administration previously announced it would examine social media accounts when vetting foreign nationals who apply for student visas or H-1B visas for skilled workers.
The state department said it would conduct "online presence" reviews for applicants and their dependants, and that privacy settings on all social media profiles must be made "public" so this screening can take place.
An announcement on the website for the US Embassy and Consulate in Mexico states certain visa applicants must list all social media usernames or handles of every platform they have used in the last five years.
It warns that if any social media information is not listed, it could lead to both current and future visas being denied.
A senior state department official said of the student visa policy: "It is an expectation from American citizens that their government will make every effort to make our country safer, and that is exactly what the Trump Administration is doing every single day."
Officers were instructed to screen for those "who advocate for, aid, or support designated foreign terrorists and other threats to national security; or who perpetrate unlawful anti-Semitic harassment or violence".
As part of the administration's broader effort to toughen borders, officials recently said an existing travel ban - affecting 19 countries in Africa, the Middle East and the Caribbean - could soon be expanded.
That move was announced in the wake of a shooting of two National Guard members in Washington DC, in which an Afghan man is accused.
Experts have previously suggested the changes to travel policies introduced under Trump have had an impact on the American tourism industry.
Earlier this year, the World Travel & Tourism Council said the US was the only one of 184 economies that it analysed that was expected to see a decline in international visitor spending in 2025.
Other Trump administration policies have also appeared to affect tourism to the country, such as many Canadians boycotting US travel as a form of protest against Trump's tariffs.
October marked the 10th straight month of decline in the number of Canadian travellers to the US.
In the past, Canadians have made up about a quarter of all international visitors to the US, spending more than $20bn a year, according to the US Travel Association.

Foreign tourists will just spend their money in other countries.
