US authorities have ordered an indefinite suspension of entry-visa processing for 75 countries while consular procedures are reassessed, with the measure due to begin on 21 January according to reporting that cites a Department of State memo. The list includes Brazil, Russia, Iran and Afghanistan and is described as an effort to tighten screening of applicants who might become a public charge. The move may delay visa interviews and travel plans for affected nationalities and could lengthen processing times more broadly; those applying for US visas or booking travel should check the US consulate website for updates and appointment availability. Those awaiting US entry documents should be aware that timelines are now uncertain and monitor official guidance.
