If you're applying for a green card (lawful permanent residence), you may come up against a hurdle if you are found to be inadmissible. Being inadmissible means that, despite meeting the basic eligibility requirements for the benefit you're seeking, you have some characteristic that's on the list of grounds of inadmissibility found in Section 212 of the Immigration and Nationality Act (I.N.A.). But in certain situations, people who are inadmissible can apply for a waiver, using Form I-601, basically asking U.S. Citizenship and Immigration Services (USCIS) to forgive the problem and grant the green card anyway.
In some cases, however, the waiver can only be granted based on a relationship that the intending immigrant has with a U.S. citizen or lawful permanent resident alien, combined with the extreme hardship that would result to those relative(s) if the immigrant were denied admission to the United States.
Examples of things that might make an intending immigrant inadmissible include having committed certain crimes, committed fraud in order to obtain an immigration benefit (for example, used a tourist visa to enter the U.S. in order to get married), appearing likely to become a public charge (receive government assistance), or having stayed in the U.S. unlawfully for more than six months.
Not all grounds of inadmissibility can be waived. You'll need to talk to a lawyer for an individual analysis and a description of the exact requirements for the waiver.
Except in cases where an immigrant would face persecution upon departure from the United States, any hardship the immigrant him- or herself would undergo if refused the green card is usually ignored by the immigration laws. That's why, in order to obtain a waiver, the immigrant will likely have to show a blood relationship with, plus the likelihood of extreme hardship faced by, one of the following people, who are either U.S. citizens or lawful permanent residents:
Although you might be thinking how awful it would be if, perhaps, your green card was denied and your family were separated and you had to pay for traveling and maintaining two separate homes, family separation and financial inconvenience alone will not likely be viewed as constituting extreme hardship. After all, numerous immigrants whose green cards or immigration benefits are denied face the very same thing. Your hardship isn't extreme unless it's something worse than faced by others in your shoes.
Think about issues like whether your qualifying family members would face health or medical hardship if you were separated or if that person had to relocate to your home country, and about other effects of relocation such as language or cultural barriers, the likelihood of physical harm, loss of educational and job opportunities, and so forth.
Simply claiming, "They'll face extreme hardship!" isn't going to get you a waiver. Rather, you must provide documentary evidence that supports your claims and reasons for seeking a waiver. For example, gather:
You will likely need legal assistance in filing for a waiver of a ground of inadmissibility based on extreme hardship. Contact an experienced immigration attorney.
