Languages, fees and rules change — confirm with the official source linked for each state. 待核 / 'To confirm' = not yet confirmed from an official source (shown honestly, never guessed). The 2025 federal English-Language-Proficiency action is roadside out-of-service enforcement, not a state test-language mandate; states set their own written-test languages (Texas and Florida moved to English-only in 2026).
