Connecticut, US
For national security reasons, the U.S. government has strict visa issuance and admission policies, and gives immigration and consular officers broad authority to initiate lengthy background and security checks, conduct personal interviews with applicants, collect biometric information from foreign nationals, deny visas, and bar reentry. Stringent security checks are possible at each stage of travel; therefore, foreign nationals  planning to travel outside the United States should be prepared for possible delay and inconvenience.
Upon application for entry to the United States, you should expect thorough screening procedures at airports and other ports of entry. Your identity and the validity of your visa will be checked against law enforcement databases. You will be fingerprinted and photographed upon entry. You may also be subject to intensive questioning about your immigration status, travel history, the purpose of your visit, background, employment and other issues. This could include a search of your electronic devices. If you are a citizen or national of a country of interest or concern to the United States (discussed further below), you may be subject to additional levels of screening.
During these entry procedures, you must remain patient and answer all questions clearly. Before you travel, check your employer's procedures for dealing with searches of company-owned phones, laptops and other devices. During inspection, answer questions to the best of your ability. If you do not understand a question, ask for clarification before answering. Omitting or misrepresenting information can result in denial of entry, removal from the United States or even possible criminal penalties. If detained at the port of entry, you are generally not entitled to have a lawyer present, but you should ask for permission to contact Fragomen offices if the need arises. You should explain that contacting Fragomen will allow us in turn to contact your employer if further information is required.
