Check the official source

Rules change and depend on your nationality, status and history. Each tool page shows the date we last checked its rule and links to the official page. Before you act, check that page and ask your embassy or consulate, your Designated School Official (DSO) or an immigration attorney.

What the tools are

The tools count days using the rules described on their pages. Border and immigration authorities decide your actual position, and their records, your passport stamps, your I-94 and your SEVIS record prevail over anything calculated here.

Accuracy

We aim to keep the tools correct and we state only rules we could verify, but we do not guarantee the site is free of errors or up to date. Use of the information and tools is at your own risk. If you find a mistake, please tell us.
