5 Ways An Undocumented Immigrant Can Become Legal
Being undocumented in a foreign country comes with a number of challenges, including inability to work legally and access benefits, on top of the constant worry you may be sent back to your country any minute.
But is there a way out?
The following scenarios allow you to file for a Green Card application and obtain legal permanent resident status.
1. Marrying A US Citizen Or A Lawful Permanent Resident
One way to adjust your status to that of a lawful, permanent resident is if you are married to a U.S. citizen or a lawful permanent resident and file for a Green Card.
Requirements include:
- Your marriage must be bona fide, meaning you entered it in good faith, with the desire to establish a life together
- All previous marriages must be legally terminated
If you entered the U.S. legally and married a U.S. Citizen, you can apply for a Green Card as an immediate relative while still in the U.S.
This can happen regardless of how long you have overstayed your visa, provided that you were inspected and admitted into the U.S.
In this case:
- File Form I-130, Petition for Alien Relative, which serves as evidence that your marriage is legally valid
- File Form I-485, Application to Register Permanent Residence or Adjust Status, along with supporting documents
What are the challenges?
Not every entry is considered a valid admission for Green Card purposes. For example, if someone is paroled into the U.S. after inspection at a port of entry, it’s only temporary. This means they might be inspected and allowed to enter, but not officially admitted.
If you entered the U.S. legally and married a Green Card holder, you must wait for a visa to become available. Until that happens, you must return to your home country and complete the immigration process through the U.S. embassy or consulate there.
To begin the process of applying for a Green Card after marrying a lawful permanent resident and applying from outside of the U.S., file Form I-130.
What are the challenges?
If you have accrued unlawful presence in the U.S., departing to apply for a Green Card may trigger a bar to re-enter the U.S.
For example, if you stayed in the country unlawfully for more than 180 days but less than one year, you could face a three-year bar. If you stayed illegally for more than one year, this could result in a ten-year bar.
Filing a waiver before leaving the U.S. provides evidence that your spouse will suffer “extreme hardship” due to your long absence. It may waive your re-entry bar and allow you to return to the U.S. after you’ve passed your consular interview.
2. Applying For Asylum Status
Another way to become legal is to apply for asylum status. To do this, you must prove you have suffered persecution in your home country or fear being persecuted if you return, due to your:
- Political opinion
- Religion
- Race
- Nationality
- Membership in a particular social group
Whether you entered the U.S. legally or illegally, to be eligible for asylum status, you must:
- Be physically present in the U.S.
- Properly file the asylum application within a year of your last entry (there are certain exceptions).
- Be unwilling or unable to return to your home country due to past persecution or fear of being persecuted in the future.
- Not be involved in activities that can bar you from asylum such as posing a danger to U.S. security, having been sentenced for a serious crime, having been part of a group that persecuted another person based on religion, race, political opinion and other circumstances.
To start your asylum status case:
- File Form I-589, Application for Asylum and for Withholding of Removal.
- Attach the additional documents needed to support your claim.
- If you win your asylum case, you can apply for a Green Card one year later.
If your family is already in the U.S., you may add them to your asylum application form. Depending on the relationship, they can also be granted asylum.
If your family members were victims of separate persecutions, they can file for asylum status separately. If your application is denied, your family members can add you to their applications.
If your family is outside the U.S. when you obtain asylum status, file a separate application so they can join you in the U.S. This should be done within two years from the date you were granted asylum.
3. Requesting Cancellation Of Removal
If you have lived in the U.S. for an extended period and are facing removal in immigration court, you may be eligible to obtain lawful status through Non-LPR Cancellation of Removal and Adjustment of Status.
Non-LPR Cancellation of Removal is only available if you have been placed into removal proceedings. What does this mean? It means the government has initiated a legal process to deport you from the U.S. You cannot benefit from it under other conditions.
To file for a Green Card, you must meet the following criteria:
- You lived and were physically present in the U.S. for a minimum of ten years.
- Your deportation from the U.S. will cause “exceptional and extremely unusual hardship” to your spouse, child, or parent, who is a U.S. citizen or permanent resident.
- You have not violated U.S. laws and have not been convicted of certain serious crimes.
- You can show evidence of good moral character for the past ten years.
To request cancellation of removal, file Form EOIR-42B.
Also note that U.S. law allows only 4,000 Green Cards to be issued annually.
4. Applying For A U Visa
The U nonimmigrant visa was created by the Congress under the Victims of Trafficking and Violence Protection Act in October 2000.
It is given to people who have been victims of certain crimes to encourage them to cooperate with police without fear of deportation.
A U visa can provide you with legal status, employment authorization (work permit) and the possibility to apply for a Green Card under certain conditions.
To qualify for a U visa:
- The crime committed must have violated U.S. laws.
- You must have suffered physical or mental abuse as a victim of qualifying criminal activities such as abduction, hostage-taking, trafficking, involuntary servitude, domestic violence, rape, or similar circumstances.
- You must provide information about the criminal activity in question.
- You must be willing to help in the investigation of the crime.
To apply for a U visa, file Form I-918, Petition for U Nonimmigrant Status.
After you are granted a U visa, you can petition to bring your spouse and children to the U.S.
5. Serving In The US Armed Forces
You may be eligible to adjust your illegal immigrant status and apply for a Green Card or apply directly for U.S. citizenship if you have served in the U.S. armed forces during qualifying wars and conflicts, such as:
- World War I
- World War II
- The Korean War
- The Vietnam War
- The Persian Gulf War
- Operation starting September 11, 2001, including the War on Terrorism, Iraq Hostilities and Operation Enduring Freedom
To adjust your status after serving in the U.S. armed forces:
- File Form N-426, Request for Certification of Military or Naval Service.
- File Form N-400, Application for Naturalization.
Each individual scenario is unique, and your pathway to obtaining legal status as an undocumented immigrant in the U.S. may vary. To determine which pathway is right for you, contact an experienced immigration attorney.

Who Is Considered An Undocumented Immigrant?
An undocumented immigrant is a person who was born in a foreign country and who has no legal right to be in or remain in the United States.
Other terms used for an undocumented immigrant include:
- Unauthorized immigrant
- Unlawful non-citizen
- Illegal alien
How One Becomes An Undocumented Immigrant
One can become an undocumented immigrant through a variety of ways, including:
Expired Visa
In this situation, you entered the U.S. legally, with a valid nonimmigrant visa such as a tourist visa or a student visa.
When the U.S. Department of Homeland Security (DHS) officials inspected and admitted you into the U.S., they listed two dates in your Form I-94, Arrival/Departure Record:
- The date you arrived in the U.S.
- The date on which you were required to depart
If you stayed in the country after the approved length of your visit, you have overstayed your visa and have lost your lawful status.
In this case, as soon as the departure date passed, you began to accrue unlawful presence and became an undocumented immigrant.
Illegal Entry
If you entered the U.S. without inspection, you are considered an undocumented immigrant. Crossing the border without inspection by a U.S. border patrol agent automatically gives you illegal status.
The consequences of being caught by officials as an undocumented immigrant include:
- Being placed in removal proceedings and receiving an Immigration Court date
- Deportation from the U.S.
- A three to ten-year bar from re-entry to the U.S. depending on the length of your illegal stay
