An important question for foreign nationals living in the United States and being petitioned for U.S. lawful residence (a green card) through U.S. family or an employer is: Will I need to leave the country as part of having my application successfully processed? The short answer is: It depends.
Some people can stay in the United States for the entire period of applying for a U.S. green card. Others must leave the United States, even after their U.S. sponsor receives approval of their initial visa petition, while they either:
We'll address both these situations below.
Important caution: If you don't currently live in the United States, but you live in another country, the possible choice described in this article does NOT apply to you. U.S. immigration authorities prefer that people wait outside the U.S. for the entire period of applying for the green card, which includes ultimately attending an interview at a U.S. consulate in your home country. There, you will receive an immigrant visa with which to enter the U.S. and become a lawful permanent resident or green card holder.
For people who are in the United States legally, perhaps on an F-1 student visa, a temporary work visa such as an H-1B, with Temporary Protected Status (TPS), or because they have a pending asylum case, having a separate visa petition filed on their behalf might work out great. Their existing status could, depending on how long it lasts, allow them to remain in the United States while their application for a green card wends its way through the system.
But that's not true in all cases. Conflicts can arise if one's existing immigration status doesn't allow for something called "dual intent." That is, if your nonimmigrant status is premised on the idea that you plan to return home at the end of your permitted U.S. stay, and if your visa doesn't allow you to simultaneously hold an intention of remaining in the United States per a separate application, then applying for a green card could actually put your existing visa at risk. This is a highly nuanced and visa-specific area, so speak to an immigration attorney for a full analysis.
The next issue to consider is: Is an immigrant visa or green card immediately available to you? This depends on which visa category you are applying under and which country you are from.
An immigrant visa is immediately available, with no waiting list, if you are either:
In the above cases, the question of whether you need to leave the United States for further application processing is simply a question of whether you're allowed to apply for your green card through the procedure known as "adjustment of status" through a USCIS office rather than using consular processing abroad, which we'll discuss in the next section, below.
If, by contrast, you are applying for a green card through a family member or employer and your eligibility category makes you a "preference" beneficiary, then a visa is NOT immediately available to you (except in the rare event that that year's supply of visas is enough to meet the entire demand). The issue is that annual limits on visas in these categories usually create a waiting list.
Your U.S. petitioner (family member or employer) will have started the green card application process for you, by filing a petition on Form I-130 or I-140 with U.S. Citizenship and Immigration Services. Once that petition is approved, you will receive a "Priority Date," or a place on the waiting list. See How to Determine Your Priority Date for Immigration Purposes to better understand this process. The key thing to realize is that you don't receive any right to remain in the United States while you wait for your Priority Date to become current.
Unless you already have a visa or immigration status that allows you to remain in the United States legally, you must (as a preference beneficiary whose Priority Date isn't current) leave the U.S. and wait to apply for your green card through a U.S. consulate (consular processing).
If you don't leave, and you spend time in the United States unlawfully, you put your very right to receive the green card at risk, and could be found inadmissible at the final stages of applying for U.S. residence and thus barred from entry for a period of years.
Let's say you are not only eligible for a U.S. green card, but you have a current Priority Date or are otherwise immediately eligible for a visa (and thus a green card). It could be very convenient if you could stay in the United States to finish up the process. However, the only people eligible to do so, that is to adjusting status, are those who:
If you aren’t eligible to adjust because of an illegal entry or other visa violation, there's a tiny chance you can still do so if you fit within an old law called 245(i). It allows adjustment status, upon payment of a $1,000 penalty fee, to people who were:
If you are, in fact, eligible to adjust status, then you will have a right to remain in the United States just as soon as your application has been submitted to USCIS and it has acknowledged receipt. Assuming you apply for a work permit on Form I-765 (employment authorization document or EAD) along with your adjustment of status application, USCIS should send you one fairly soon, allowing you to work while you wait for the AOS interview where your application will be decided upon.
If you are out of status at the moment (you have no legal right to be in the U.S.) and you are planning to apply for adjustment of status, try to get your application in quickly. Otherwise, if you are arrested, you will have to present your application in immigration court and could be deported.
This is a difficult area of law, and figuring out whether you fit within one of the above exceptions is best done with the help of an attorney.
Look for a qualified and experienced immigration attorney who routinely handles adjustment of status cases and can explain to you the rules and your rights and assist you with the paperwork. Also see Is an Immigration Lawyer Worth the Cost?.
