Every Embassy, Consulates, or equivalents (like the American Institute in Taiwan, which is a de-facto Embassy) should be able to do this. Embassies are US soil which fulfills the legal requirements to be on US soil to request asylum. Approve. PS. International law dictates that a country can only turn back asylum seekers if the previous country the asylum seekers are passing through is designated as a “Safe Third Country”. Mexico IS NOT designated as a “Safe Third Country” by the USA. While we are at it, our agreement with Canada is in jeopardy too as there is a court case in the Canadian courts right now to remove OUR designation as a “Safe Third Country” due to the numerous human rights violations at the southern border.
