In some, there are reasons to keep you out for health reasons, criminal reasons, security reasons. Now for some of these, even though you are ineligible to be admitted to the US, individuals can apply for a waiver or forgiveness for this ground of inadmissibility. Some of the grounds of inadmissibility that could be waived are, for example, some not all, some health-related grounds, certain criminal grounds. If you're a member of a totalitarian party and you were forced to become a member of that totalitarian party. Some fraud or misrepresentation could be waived. Certain grounds of inadmissibility filed by people who've been abused by their spouses could be waived. Again, it's important to speak with an immigration practitioner to see if the person who's being barred from coming in is eligible for a waiver to be allowed to come back into the country or to come into the country for the first time. The people who could file for such waivers are people who are trying to come in as an immigrant. For example, if you're trying to apply for a green card, you were sponsored by a family member here and you have an interview at a US embassy over there and you had been found to be inadmissible, for example, on a health-related ground because you have active tuberculosis, it might be possible to file for a waiver. That waiver has to say my spouse has sponsored me, my husband, my wife in the processing in order to get a visa to emigrate to live with my spouse. It was discovered that I have active TB, but please wave that grounds of inadmissibility for the following reasons. The applicant has to show that if admitted to the US, they will seek medical assistance, for example, and that their spouse will be responsible for all medical fees. Another type of person who could file for a waiver are people who've been trafficked and they've been found inadmissible. But they're now trying to get a green card because they testified against the traffic yet they might be found inadmissible for another reason. Again, it could be a health-related reason and they might be eligible to apply for a waiver. Again, someone who is sponsored by a family member, but that family member is abusing the potential resident. If again, the resident is also found ineligible for a visa, they too might be eligible to file for a waiver. In addition to people who are applying for immigrant visas, there are some people who are trying to come in on a non-immigrant visa, such as the fiance over US citizen. But again, if it pops out that they have a ground of an admission, health, or certain crime, or membership of a totalitarian party, again, they can apply for a waiver. It's not guaranteed that they will be given one, but they might be able to apply for a waiver. Depending on the facts and the advocacy stated in the facts, the waiver may be granted and that fiance might be allowed to come into the US and marry their petitioner. In order to file for a waiver, applicants must complete immigration form I-601. There they would provide information about themselves and give a detailed description of why they believe they should get a waiver from any one of the grounds of an admission. In some, people are allowed to come into a country as a non-immigrant or as an immigrant being sponsored by a family member, an employer, or asking for refuge, or winning the diversity visa program, or being an unaccompanied minor, as we have discussed in previous Coursera sessions. But if they fall under any one of the grounds of exclusion, they will not be admitted into the country.
