About

Visa Countdown

Read full description

Visa Countdown turns an expiry date into a full timeline, so you always know which step is next. 【A timeline, not just a date】 Pick a visa type, enter the issue and expiration dates, and the app builds every milestone from real immigration rules: extension windows, status expiry, grace period end, renewal preparation. It covers 19 visa types — H-1B, F-1, OPT, L-1, TN, J-1, O-1, Green Card, Canada work and study permits, Express Entry, UK Skilled Worker and Student, Australia 482 and Student 500, and Schengen. 【Know what to prepare】 Each of the 78 milestones carries its own document checklist (Form I-129, I-20, DS-2019, CoS, OSHC and more) plus the official link, so you land straight on USCIS, GOV.UK, IRCC or Home Affairs instead of searching for it. 【Reminders on your schedule】 Choose 1, 3, 7, 14 or 30 days before expiry — or add your own — and get one more reminder on the day of each milestone. The To-Do tab pulls every milestone from all your visas into one list, grouped Overdue, Next 30 days and Later. 【Also】 · Days remaining, validity progress ring, and days overdue when a visa has lapsed · Search across visa names, notes and milestones · Archive a record, or undo a delete right after · Import and export your data as JSON when you change phones · 15 languages plus Follow System; dates always use the Gregorian calendar with month names in your language · No account needed — your records stay on your device The free version stores 1 record and includes the F-1 student visa. Upgrade to PRO to unlock all 19 visa types, unlimited records, renewal checklists with official links, and data import and export. 【Subscription & one-time purchase】 · Available as an auto-renewable annual subscription or a one-time lifetime purchase; prices are shown on the App Store purchase screen · Payment is charged to your Apple ID account on purchase confirmation · The annual subscription auto-renews unless auto-renew is turned off at least 24 hours before the end of the current period; renewal is charged within 24 hours before the period ends · Manage or cancel auto-renewal any time in iPhone Settings → Apple ID → Subscriptions · The Lifetime plan is a one-time purchase that permanently unlocks PRO and does not auto-renew Privacy Policy: https://huanhua2025.github.io/privacy-policy/Visa%20Countdown.html Terms of Use : https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
