"apply to immigration" / "submit documents to customs"
"appear in court" / "bring a case before a judge"

Tip
Common mistakes to avoid
Watch out for these universal errors when using authorities vocabulary:
Using the wrong preposition: say "report to the police" or "report something to the police", not "report the police".
Mixing singular/plural with collective nouns: 'the police' is treated as plural (e.g., 'the police are'), while 'a police officer' is singular.
Incorrect collocations: prefer 'file a report' or 'make a complaint' rather than mixing verbs and nouns incorrectly.
Confusing which authority to contact: choose the correct body (e.g., call the fire department for fires, not customs).
Double-check prepositions, collocations, and subject-verb agreement.
