Under Immigration Law, people with certain characteristics are not allowed to enter U.S.with a visa or green card, which is called inadmissible. Generally speaking, people with histories of criminal or terrorist activities, drug abuse, infectious medical problems, or certain other characteristics are considered inadmissible aliens. Some of the grounds may receive official waiver, which forgives or overlooks the inadmissibility. Grounds for admissibility include three categories shown as listed in the following list.
Classes of Grounds of Inadmissibility Waivers Available?
People with communicable diseases like tuberculosis Yes
People with physical or mental disorders that
may cause harm to themselves or others Yes
Drug abusers or addicts No
Drug traffickers No
People without proper vaccinations Yes
People with convictions for crimes involving moral turpitude Yes
People who have violated immigration laws Yes
People with multiple criminal convictions Yes
People likely to become dependent on
need-based government assistance No
US consulate, Customs and Border Protection (CBP) and US Citizenship and Immigration Services (USCIS) may decide a person is inadmissible at time of application. If you are a U.S. border when this occurs, will be turned around and sent home. If you're in the United States, you will, if you have no other visa or status, be sent to immigration court for removal from the United States.
Even a permanent resident (green card holder) might be found inadmissible. If a permanent resident departs the United States for more than 180 days, it's possible for him or her to be found inadmissible upon return. This situation might arise, for example, if the person had committed a crime, had developed tuberculosis, or had begun receiving public assistance since receiving the green card.
Even if you fall into one of the categories of inadmissibility, you may not be absolutely barred from getting a green card or otherwise entering the United States if a waiver is averrable to you. You may ultimately need to hire a good immigration lawyer. You are welcome to contact us for details.
