(CNN)Here's a look at visas, travel documents for individuals who are visiting or moving to the United States.
Facts
A visa is a travel document, affixed to a passport, granting citizens from foreign countries permission to enter the United States for a certain purpose, whether it's a business trip, a family vacation or a student exchange program. Unlike passports, visas are issued by the country a traveler is intending to visit.
There are dozens of different types of visas covering an array of travel purposes and countries of origin.
Nonimmigrant visas are for visitors and temporary workers, and immigrant visas are for individuals who are relocating to the United States permanently.
A visa, approved by a consular officer in the traveler's home country, does not guarantee admission to the United States. Officials from Customs and Border Protection (CBP), on behalf of the Department of Homeland Security (DHS), may deny a traveler permission to enter the United States for a variety of reasons, even if the individual has a valid visa.
Visitor visas can be used for multiple trips to the US while the visa is valid. CBP determines the length of stay for each visit. With most tourists and business travelers, the maximum length of stay per trip is six months. Visitors must return home when the approved length of stay ends, unless they've been granted an extension by US Citizenship and Immigration Services (USCIS).
According to DHS, the rate of suspected overstays for business travelers and international tourists was 3.67% in FY 2022. That calculates to 853,955 overstays.
In fiscal year 2022, the United States issued 6,815,120 nonimmigrant visas and 493,448 immigrant visas, according to preliminary data.
Nonimmigrant Visas:
The nonimmigrant visa application process begins with an online application called the DS-160 form. After submitting the form, applicants must call the nearest embassy or consulate to schedule an interview.
Some nonimmigrant visa applicants may have to pay an additional fee when their paperwork is approved, depending on their nationality and the fees imposed by their home country on travelers from the United States. This is called the principle of reciprocity.
The United States has a Visa Waiver Program. Individuals from 40 participating countries, including the UK, France, Japan, Australia and Chile, are permitted to travel to the United States for tourism or business without a visa. The waiver only covers stays of 90 days or less.
There are more than 20 major categories of nonimmigrant visas, covering different reasons for travel. The five most common types are business travel/tourism visas (B-1, B-2), student visas (F, M), exchange visitor visas (J), crew member/transit visas (C-1/D) and specialty worker visas (H-1B).
B-1/B-2: These are visitor visas for travelers coming to the United States for business (B-1), tourism/vacation (B-2) or a combination of both.
F: This visa is for students coming to the United States to attend grade school, college, seminary or other types of academic institutions. Students have 60 days to leave the United States after they have completed their studies.
J: Issued to participants in private sector cultural exchange programs. Cultural exchange categories include scholars, interns, teachers, seasonal workers, au pairs and professional trainees.
C-1/D: This visa is a combination crew member/transit visa issued to employees of airlines and cruise ships whose jobs involve continuous travel in and out of the United States. The C-1 visa is a transit visa, while the D visa is for crew members. Both visas are required for workers who come from other countries to work on a United States-based ship or aircraft.
H-1B: This visa is for specialty workers, highly skilled professionals in fields including engineering, technology, medicine and higher education. There are three subcategories of H-1B visas. The H-1B1 is a free trade agreement visa for specialty workers from Chile and Singapore. The H-1B2 is for specialists who will work on projects for the Department of Defense Cooperative Research and Development program. The H-1B3 visa is for fashion models of "distinguished merit and ability."
Immigrant Visas
The immigrant visa application process begins with a petition, which must be approved by US Citizenship and Immigration Services. Once the petition is approved, the applicant pays fees and files paperwork with the National Visa Center. After the documents are submitted, an interview is scheduled with an officer at the nearest US embassy or consulate. At the end of the interview, the applicant is told whether he or she has been approved or denied.
The main categories of immigrant visas are Immediate Relative (IR), Family Preference (F), Diversity Immigrants (DIV), Employment Preference (E) and Special Immigrants (SIV).

Diversity visa applicants must have a high school education or at least two years of qualifying work experience.

In some cases, an applicant who doesn't have a specific job offer may file a petition on his or her own behalf. There are five categories for these visas.
