What this guide resolves
Understand when to extend, what proof of submission means and why a pending application may not protect lawful stay.
Documents to compare
Place the passport, visa approval, visa label, entry stamp, visitor permit and extension receipt side by side. Record every date and note which authority issued it.
When to seek confirmation
Contact the official authority when dates conflict, an endorsement is unclear, a passport was replaced, the traveler left and re-entered, or an extension is pending.
Practical rule
Never rely on a flight itinerary, hotel booking or agency message as proof of immigration status. The official document or authority record controls.
Confirm traveler-specific dates through the issued document and responsible immigration authority.
