1. Basic understanding of US immigration visas
An immigrant visa is a visa that allows a foreigner to reside permanently in the United States. This is clearly different from a non-immigrant visa, which is for tourism or a short-term stay. If you enter the United States with an immigrant visa, you are eligible to obtain a green card.
U.S. immigrant visas can be broadly divided into visas based on family relationships, visas based on employment ability, and visas based on special circumstances.

4. Other immigration visas
U.S. immigration law sometimes provides permanent residence opportunities to foreign nationals who have very special and exceptional circumstances. The visas mentioned in the “Other Immigrant Visas” section are for these cases, based on a special interest or need for protection of the United States, rather than the individual’s general background or ability.
-
Foreign nationals recognized for special merit (Special Immigrant Visas): This category is very diverse and may be available to foreign nationals who have made extraordinary contributions to a particular U.S. interest. Some examples include:
- Religious Workers (EB-4): As previously mentioned, foreign nationals who are engaged in religious occupations, such as pastors, priests, and monks, may apply for permanent residency if they meet certain requirements. They must perform their duties at the request of a non-profit religious organization.
- U.S. Military Service Members (EB-4): Foreign nationals who have served in the U.S. military for a certain period of time, or their spouses and children, may also apply for permanent residency through a special immigrant visa. This is a form of compensation for foreign nationals who have contributed to the security of the United States.
- International Organization Staff and Family Members (G-4 Staff and Certain Relatives): Foreign nationals who have held or are holding important positions in certain international organizations and their immediate family members may also be eligible for a special immigrant visa.
- Specific information provided at the request of the U.S. Government: Special immigrant visas may also be available to foreign nationals and their family members who have provided information critical to U.S. law enforcement or national security.
-
Victims of Trafficking in Persons (T Visa): The T visa is a nonimmigrant visa designed to protect foreign nationals who have been victims of severe forms of human trafficking, such as forced labor or sex trafficking. Holders of a T visa are legally permitted to reside in the United States, obtain work authorization, and, if certain conditions are met, are eligible to apply for permanent residency. The primary purpose of the T visa is to encourage victims to leave their abusers, secure safety, and cooperate with the investigation of a crime. Applicants must demonstrate that they have been victims of human trafficking and have cooperated or are willing to cooperate with law enforcement in the investigation. Certain family members, such as spouses, children, parents, and siblings, may also receive T visa derivative status.
-
Victims of Domestic Violence (U Visa): The U visa is a nonimmigrant visa that protects foreign nationals who are victims of certain crimes, including domestic violence, and certain of their family members. U visa holders are legally permitted to stay in the United States, obtain work authorization, and are eligible to apply for permanent residency if they meet certain conditions. The purpose of the U visa is to encourage crime victims to seek safety and cooperate with law enforcement in their criminal investigation. Applicants must demonstrate that they have been victims of a crime and have cooperated or are willing to cooperate with law enforcement in their investigation. Certain family members, such as spouses, children, parents (for minor children), and siblings (for minor children), may also receive U visa derivative status.
-
Special Immigrant Juvenile Status (SIJ): SIJ is a special category that provides a path to permanent residence for certain minor aliens who are unable to obtain parental care due to abuse, abandonment, or neglect in the United States. SIJ applicants must prove this situation through a domestic relations court decision in the United States, and must meet certain age requirements when applying for permanent residence.
As such, the “other immigration visa” categories are very diverse, each with its own unique eligibility requirements and application procedures. If you are considering one of these visas, it is important to consult with an immigration law professional for accurate legal advice.
5. Overview of the immigration visa application process
The process of applying for a U.S. immigrant visa can vary in detail depending on a variety of factors, including the type of visa being applied for, the applicant's current residence, and whether or not there is a sponsor in the U.S. However, it generally goes through the following major steps. Since the required documents and time periods vary for each step, it is important to check and prepare sufficient information in advance.
-
Filing an Immigration Petition: The immigration process begins when the person sponsoring the applicant (family member or employer) in the United States files an immigrant petition with the United States Citizenship and Immigration Services (USCIS). The appropriate petition form, such as Form I-130 for family-based immigration or Form I-140 for employment-based immigration, is filled out and submitted to USCIS along with the required supporting documentation. The required fee must be paid when filing the petition.
-
Approval of immigration petition: USCIS reviews the submitted immigrant petition to determine sponsorship eligibility and relationship to the applicant. Additional documentation or information may be requested during the review process, and if all requirements are met, the petition will be approved. A petition approval notice (Form I-797) will be sent to the sponsor and the applicant.
-
National Visa Center (NVC) Process: Once the immigrant petition is approved, the case is transferred to the National Visa Center (NVC) for the next step in issuing the applicant’s visa. The NVC will guide you through paying the visa fee, submitting the Affidavit of Support (I-864), and preparing and submitting various civil documents, such as the applicant’s birth certificate, marriage certificate, and police records. The NVC will manage the case until the applicant is deemed ready for an interview.
-
Interview with the U.S. Embassy in Korea: Once all procedures at the NVC are completed, the applicant will be notified of the date and time for the immigrant visa interview at the U.S. Embassy in Korea. On the day of the interview, the applicant must bring the original and translated copies of all documents submitted to the NVC, as well as any additional documents requested by the Embassy. The interview will examine the applicant's immigration purpose, the sincerity of the relationship with the sponsor in the U.S., and the applicant's eligibility for entry into the U.S.
-
Visa Issuance and Entry into the United States: If you pass the interview and meet all requirements, an immigrant visa will be issued in the applicant's passport. The visa issued will specify the period of validity for entry into the United States, and you must enter the United States within that period. Upon entering the United States, you will undergo a final examination by an immigration officer and subsequent procedures for obtaining a permanent resident card (green card) will be carried out. Typically, a permanent resident card will be mailed to you within several weeks to several months after entering the United States.
The US immigration visa application process can be complex and time-consuming, so it is important to be thorough and prepare thoroughly for each step. If necessary, it is also a good idea to seek the help of a US immigration law expert.
6. Precautions and Restrictions
- Waiting period by visa type: For family-based immigrant visas, the waiting period can be very long, depending on the type and priority of the visa. Employment-based immigrant visas may also have a waiting period due to quota restrictions.
- Application Eligibility Requirements: You must meet the qualification requirements for each visa type, including education, work experience, and family relationships.
- disqualification: Your visa may be denied if you have certain disqualifying factors, such as a criminal record or communicable disease.
- Provide accurate information: Providing false or inaccurate information during the visa application process may result in disadvantages.
