	Introduction

In 1970, the K visa category was created for foreign national fiancé(e)s of U.S. citizens. The first visa within the category, the K-1 visa, is a nonimmigrant visa that grants temporary admission to the United States for fiancé(e)s in order for them to marry their U.S. citizen petitioners. Since the visa's creation, Congress has passed additional legislation that has added protections for fiancé(e)s and their children. There were 35,925 K-1 visas issued by the U.S. Department of State (DOS) in FY2014. The K-1 visa has drawn increased attention due to a mass shooting in San Bernardino, CA, on December 2, 2015. Some members of Congress have also called for the inclusion of visa applicants' social media accounts as an added screening measure. Next, the report will cover the requirements of the visa and its application procedures, including the filing of a petition, the application for a visa, and the national security screening. Background

P.L. 91-225 established the K nonimmigrant visa category in 1970 for fiancés, fiancées, and the derivative children of the fiancé(e). The K-1 visa is for noncitizens seeking to enter the United States to marry a U.S. citizen, and the K-2 visa is for their children. 109-162 ) requires the disclosure of the use of an international marriage broker and the petitioner's criminal convictions for certain crimes, notably sexual crimes. Requirements and Procedures

In order for a foreign national to be issued a K-1 visa, the petitioner who is filing on the fiancé(e)'s behalf must be a U.S. citizen and must provide the following evidence: 
The parties have met in person within two years of the petition's filing, though the Secretary of DHS may waive this requirement. The parties have a bona fide intention to marry. The parties are legally able and willing to conclude a valid marriage in the United States within 90 days of the fiancé(e)'s arrival. Citizenship and Immigration Services (USCIS), along with supporting documents. Apply for a Visa

After USCIS approves a petition, it is sent to the U.S. Embassy or Consulate in the home country of the foreign national to determine eligibility for a K-1 visa for admission to the United States. CCD links with other databases to flag problems that may have an impact on the issuance of the visa, which include DHS's Automated Biometric Identification System (IDENT) and the Federal Bureau of Investigation (FBI) Integrated Automated Fingerprint Identification System (IAFIS). To screen K visa applicants, as well as all other visa applicants, consular officers use the Consular Lookout and Support System (CLASS) database, which has name-searching algorithms to ensure matches between names of visa applicants and any derogatory information contained in CLASS. If consular officials receive information about a K visa applicant that causes concern, they send a dedicated and secure communication to the National Counterterrorism Center (NCTC). In June 2013, DOS began "Kingfisher Expansion" (KFE) in partnership with the NCTC for conducting interagency counterterrorism screening of all visa applicants. DHS initiated three pilot programs earlier in 2015 to specifically incorporate appropriate social media review into its vetting of applicants for certain immigration benefits. Once in the United States, the K-1 nonimmigrant is required to marry the U.S. citizen petitioner within 90 days. This status is conditional for two years.
The K nonimmigrant visa category was created in 1970 through P.L. 91-225, which amended the Immigration and Nationality Act (INA). Within the K visa category, the K-1 visa is a visa for fiancé(e)s of U.S. citizens and the K-2 visa is a visa for the fiancé(e)'s children. Congress later enacted legislation to provide protections for fiancé(e)s, specifically creating requirements around the use of international marriage brokers, the disclosure of the U.S. petitioner's criminal background, the provision of information to fiancé(e)s on their rights, and additional protections for minors.
A mass shooting on December 2, 2015, in San Bernardino, CA, where one of the suspected shooters entered the United States on a K-1 visa, has drawn increased attention to the visa category. This tragedy has spurred questions surrounding the K-1 visa national security screening process and any possible gaps. Some Members of Congress have suggested including a review of K-1 applicants' social media accounts into the screening process.
In order to qualify for a K-1 visa, a U.S. citizen must file on behalf of his/her fiancé(e) and provide evidence that (1) the parties have met in person within two years of the petition's filing, (2) the parties have a bona fide intention to marry, and (3) the parties are legally able and willing to be married in the United States within 90 days of the fiancé(e)'s arrival. The petitioner must first file a petition with the Department of Homeland Security's (DHS's) U.S. Citizenship and Immigration Services (USCIS). Once the petition is approved, it is sent to a U.S. Embassy or Consulate in the home country of the foreign national, where it is determined if the fiancé(e) is eligible for admission to the United States. Although the K-1 visa is a nonimmigrant visa, the fiancé(e) intends to remain in the United States and is therefore also subject to the admission requirements of immigrant visas.
K visa applicants' national security screening entails the use of biographical, biometric, and photographic data. The data are entered into consular-based databases, such as the Consular Consolidated Database (CCD) and Consular Lookout and Support System (CLASS), which flag problems that may have an impact on the issuance of a visa or matches to any derogatory information. Consular offices send suspect individuals' applications for greater review to other agencies, such as the Federal Bureau of Investigation (FBI) and the National Counterterrorism Center (NCTC). In 2013, NCTC began conducting interagency counterterrorism screening of all visa applicants and in 2015, DHS began pilot programs to incorporate social media screening into its vetting of applicants for certain immigration benefits.
Once visa applicants have been approved and their security clearances are completed, they can travel to the United States, where they must marry their U.S. citizen petitioners within 90 days of their arrival. Once married, the fiancé(e) adjusts to a conditional residency and after two years can become a lawful permanent resident.
In FY2014, the U.S. Department of State issued 35,925 K-1 visas. Asia received the largest portion of K visas at 46%, with the Philippines being the country with the highest number of K visas at 8,525 visas.
