Who Is Eligible for a Family-Based Green Card?

Uniting U.S. citizens and lawful permanent residents (green card holders) with their overseas family members is an important goal of U.S. immigration law. But that doesn't mean that every relation of a U.S. citizen or permanent resident will qualify for a U.S. green card. The law sets strict guidelines for which family relations are green-card eligible—and in some cases, for how many people will be allowed into the U.S. per year based on that category. The result is that you'll need to plan for possible delays, and perhaps implement step-by-step strategies for ultimately reuniting your family in the United States, as described here.

Immediate Relatives of U.S. Citizens Can Immigrate Right Away

An unlimited number of green cards can be issued to immigrants who are immediate relatives of U.S. citizens, which means they need not deal with waiting lists based on high demand. Immediate relatives are defined as:

• spouses of U.S. citizens, including recent widows and widowers and (as of 2013) same-sex couples whose marriage is legal in the state or country where it took place
• unmarried people under the age of 21 who have at least one U.S. citizen parent
• parents of U.S. citizens, if the U.S. citizen child is over the age of 21
• stepchildren and stepparents, if the marriage creating the stepparent/stepchild relationship took place before the child's 18th birthday, and
• parents and children related through adoption, if the adoption took place before the child reached the age of 16. All immigration rules governing natural parents and children apply to adoptive relatives, but there are some additional procedures to be followed.

The U.S. citizen sponsor starts the immigration process by petitioning on Form I-130, issued by U.S. Citizenship and Immigration Services (USCIS). After that, the immigrant submits additional paperwork and most likely goes through "consular processing" to receive a U.S. immigrant visa (the equivalent of a green card). Or in some cases, where the immigrant is already in the U.S. (ideally in lawful immigration status), that person need not leave, but can apply to USCIS for "Adjustment of Status" on Form I-485 and attend an interview at a USCIS office in order to receive permanent residence. In fact, it's possible in many immediate-relative adjustment cases for the family to submit the I-130 and I-485 packets to USCIS all at once, or "concurrently." (Also see Getting a Green Card: Consular Processing vs. Adjustment of Status.)

Fiancé(e)s of U.S. citizens are also just a few steps away from a green card. But if the fiancé is overseas and the couple wishes to hold the marriage in the U.S. before applying for a green card, the first step is to apply for a temporary (90-day) U.S. visa called a K-1 fiancé visa. After the marriage, the immigrant can apply directly to USCIS for "Adjustment of Status" on Form I-485 and, following the USCIS interview, receive what's called "conditional permanent residence," which should eventually lead to permanent residence.

Other, "Preference" Relatives of U.S. Citizens and Permanent Residents Can Immigrate If and When Enough Visas Are Available

Certain other family members of U.S. citizens or permanent residents are also eligible for U.S. green cards. However, only a limited number of green cards are available to these applicants. They typically have to wait many years to get them, based on their place in the following preference categories:

• Family first preference. Unmarried people, any age, who have at least one U.S. citizen parent.
• Family second preference. 2A: Spouses of green card holders and unmarried children under age 21; 2B: unmarried sons and daughters (who are over age 21) of green card holders.
• Family third preference. Married people, of any age, who have at least one U.S. citizen parent.
• Family fourth preference. Sisters and brothers of U.S. citizens where the citizen is over 21 years old.

As described above, the U.S. family member must start the process by petitioning for the immigrant on Form I-130. Following USCIS's approval, however, the intending immigrants might have to wait several years until their "priority date" is current and they can move forward (also following the same process described above).

Where the Line Gets Drawn on Which Family Members Can Immigrate

U.S. immigration law offers no direct way to obtain U.S. green cards for one's grandparents, aunts, uncles, nieces, nephews, and more extended relations—unless you can create a chain of relationships so that a more immediate family member can petition for them.

For example, instead of petitioning for a grandparent, a U.S. citizen could petition for his or her parents; and they could, after receiving a green card and eventually U.S. citizenship, petition for their parents (your grandparents). But this strategy almost always requires long-term planning, because obtaining both a green card and eventually U.S. citizenship tends to take several years, depending on a variety of factors.

One important variable is that, in the visa categories subject to annual limits (in what is called the "preference" categories), the number of people applying almost always exceeds the supply of available visa numbers (green cards). The result is that applicants must typically wait a long time until a visa number is available. The average wait is from five to 25 years, depending on the visa category and the country from which the immigrant is applying (due to per-country limits). In recent years, however, there have been visas available in category 2A with little to no wait.

A Change in Marital Status Can Create Problems for Would-Be Child Immigrants

Keep in mind that every immigrant must fit the eligibility criteria all the way up through their approval for adjustment of status or entry to the U.S. on an immigrant visa. If, for example, someone immigrating as an unmarried child gets married in between receiving their U.S. visa and entering the United States, they will be denied entry. See an immigration attorney if you encounter complications like these.
