Refugees are often admitted into the US because conditions in their home country are difficult and pose a hazard. However, there is often an ethical dilemma when a refugee applicant is found to be inadmissible to the US due to criminal convictions or health issues which would make anyone inadmissible into the US. A refugee applicant who has such issues which lead to inadmissibility can apply to have these inadmissibility grounds removed by filing USCIS Form I-602 (Application By Refugee For Waiver of Grounds of Excludability). However, the refugee applicant will need to show on the application that an exception should be made due to national interest, humanitarian reasons, or family unity reasons.
