When to get professional help
- Ask the responsible counter or provider when a document is rejected or a deadline was missed.
- Use a licensed tax accountant for uncertain residence status, overseas income/assets, or a final return.
- Use an immigration professional for residence-status or work-permission questions; this roadmap does not decide visa eligibility.
