United Kingdom
Since 22 July 2025, new Skilled Worker applicants generally need a job classed as ‘higher skilled’ (RQF level 6+). Jobs classed as ‘medium skilled’ are only eligible if they appear on the Immigration Salary List or Temporary Shortage List, so check the current eligible occupations list for this job’s occupation code. Some nationalities can use the Youth Mobility Scheme instead. Skilled trades in the UK are typically classed at RQF level 3.
