Travel Days & N-400 Tracker

Why Track Your Travel Days?

Whether you are an expatriate working your way towards US Citizenship, or a digital nomad hopping between countries, immigration authorities and tax bodies count physical days strictly.

The USCIS N-400 Requirements

If you are applying for US citizenship through naturalization using the standard 5-year route, you must satisfy two primary physical presence constraints:

• Physical Presence Limit: You must have been physically present in the United States for at least 30 months out of the 5 years (which translates to strictly no more than 913 days outside the US).
• Continuous Residence (6-Month Rule): If you take a single trip outside the United States that lasts more than 180 days (6 months), it automatically disrupts your continuous residence, potentially resetting your 5-year clock.

The Digital Nomad 183-Day Tax Rule

Most countries worldwide utilize the "183-day rule" to determine your tax residency. If you stay within a country's borders for 183 days or more in a given calendar year (or rolling 12-month period), you are legally recognized as a tax resident of that country and are subject to local income taxes on your global income.

Using our calculator, you can log all your trips and ensure your maximum trip length never breaches this critical threshold, protecting you from double taxation. All dates entered are calculated locally in your browser.
