Why we built these tools

The same questions reach us every week: when can I apply for citizenship, when do I file to remove conditions, how long can I stay abroad, and how does the E-2 visa work. These tools answer the first part in a minute, using the rules that USCIS and the State Department publish. When your situation has a complication, the result gives you a clear starting point for a conversation with a lawyer.

Frequently asked questions

Are these immigration tools free?

Yes. All of the tools are free to use and do not require an account or an email address.

Do you store the dates I enter?

No. The calculations run in your browser. Nothing is sent to Ozek Law Firm unless you choose to press “Send to Ozek Law,” which opens an email that you review before sending.

Can I rely on a calculator instead of a lawyer?

A calculator applies the general rules to the dates you enter. It cannot see your full immigration history, criminal or tax issues, or exceptions that may apply. Use the result as a starting point and have an attorney review your case before you file or travel.

Want a lawyer to check your dates?

A calculator gives an estimate. We review your full history, including trips, prior status and any complications, before you file.
