That’s true, but making the test significantly harder could unintentionally create barriers for people who are already integrated and contributing to society. Also, the process itself, with interviews, residency checks, language requirements, and background screening is already detailed and can feel overwhelming for many applicants.
If the goal is to help people really belong, maybe the discussion should be about supporting applicants with better resources for language learning and civics education instead of making the formal requirements tougher.
