A 10-year visa doesn’t mean you can stay in the country that long, and marrying a US citizen doesn’t grant immediate status. People believe these myths, waste time and money, or even risk their immigration status. We break down five common misconceptions about US immigration and how the system actually works.

A visa and a period of stay are different things

Most people who get tourist visas think the visa’s validity period is how long they can stay in the US. In the US, the system works differently. The visa expiration date is simply the window during which you can travel to the country. How long you’re allowed to stay after arrival is decided by the officer at the border.

If you arrive on a tourist visa with no violations on previous trips, the chances of getting authorized for 180 days are high. The date in your passport barely matters: even if your visa expires on December 31, 2026, and you arrive that day, the officer may still grant you another 180 days from the moment of entry. The visa is valid — but that doesn’t entitle you to the same amount of time in the country.

Marrying a US citizen is only the start of the process

Marrying an American citizen is a first step, not a guarantee. The marriage itself doesn’t grant status and doesn’t trigger a green card.

After registering the marriage, you need to obtain a Certificate of Marriage. Then the spouse files a petition with the immigration service for family reunification — it’s the US citizen who files it, not the foreign spouse. The petition must prove the marriage is genuine, not fraudulent.

Even after the petition is approved, a separate question arises: can you get your green card inside the US or abroad? That requires individual analysis, especially if you have violations in your immigration history.

A US citizen child can only help you at age 21

Being born in the US automatically gives a child American citizenship. But that gives the parents no legal status in the country and doesn’t protect them from deportation.

The main problem: people have US citizen children, lose their own status, and wait for deportation hearings. During that wait, they remain in the country unlawfully. Even if you have a US citizen child, a court may not treat that as a mitigating factor and may still order removal.

A child can only help sponsor you for a green card once they turn 21. Until then, you have no direct path to legal status based solely on their citizenship. If you’re deported before they reach adulthood, reentering later will be harder or impossible.

A visa denial isn’t a ban on future attempts

A denied visa or petition doesn’t mean you can no longer file anything. There are virtually no limits on how many times you can reapply, as long as you have the money and willingness to keep filing.

There is one catch, though: everything you’ve ever submitted to a US government agency stays in the system forever. If you disclosed information about your past in one application, it will be available to the officer reviewing the next one — even if 10 or 20 years have passed.

Withdrawing an earlier application won’t hide the information. For example, if you filed a petition for political asylum and later decide to apply for a work visa, the officer will still see both filings and compare the information in them. This can become a problem if the data contradicts itself.

Fabricated evidence is risky even with a green card or citizenship

If you obtained a green card or citizenship using fake or fabricated evidence, it can be revoked — even years later.

Examples of problematic documents: a fake diploma, recommendation letters supposedly from people who never wrote them, awards you never received. If a US government agency later finds a significant discrepancy between what you submitted and reality, it can start the process of revoking your status.

This isn’t a simple procedure — judicial resources will be involved. But if it’s proven that the information was a material factor in the decision, you could lose both your green card and your citizenship. Before falsifying any documents, it’s worth genuinely weighing the risk and its consequences.
