A 2019 report by MigrationWatch condemned the Conservative government's approach to immigration, stating that its "flaccid proposals have no prospect of achieving a significant reduction in the level of net migration". It has called Britain's port security "resourced to fail" in stopping illegal immigration, and has opposed the idea of an amnesty for illegal immigrants in Britain, after it was postulated by Prime Minister Boris Johnson. The group criticised the same government for extending the period in which overseas students can stay in the UK from four months to two years, arguing that it would "likely lead to foreign graduates staying on to stack shelves". It has also been critical of proposals by Boris Johnson to scrap the £30,000 salary cap on migrants, warning that abolishing the cap could lead to further rises in migration.
