Immigration control in the UK is managed within a Common Travel Area (CTA). The CTA is an intergovernmental agreement that allows free movement in an area including the United Kingdom, the Isle of Man, the Channel Islands (Guernsey, Jersey, Sark and Alderney) and the Republic of Ireland. The authorized entry to one of the above points essentially allows entry to all others, but it is the responsibility of the incoming person to ensure that they are properly documented for entry into other parts of the CTA. Despite the CTA, it is still possible to be deported from the United Kingdom to the Republic of Ireland and vice versa. Among the many jobs in the regions is the recruitment of 100% of passengers arriving at ports or airports for immigration checks. Officers also conduct risky wiretaps for controlled drugs, cash, tobacco, alcohol, firearms, offensive weapons, prohibited goods, counterfeit goods and illegal participants. They do so for passenger and cargo checks that cover passengers travelling on foot, by car, coach, coach, cargo, air freight and shipping containers. Officers have a set of powers vested in them by their status as designated immigration officers and customs officers. Border guards are agents. The teaching element is a three-week program that combines assessment, role-playing, live and theoretical testing.
Border management in the United States is an equivalent system operated by that country with the UKBF at some airports outside the United States. UKBA has had an eventful history. There were difficulties in managing student visas according to Level 4 of the points-based system. The independent Chief Inspector`s assessment, conducted between July and August 2010, revealed an inconsistent response to applications, with additional preparation periods and other minor reasons being made redundant.  Historically, port and domestic immigration officials have received different training to reflect these different approaches to immigration implementation, which are now reinforced by national officials working for the Immigration Office, which is a separate home service. All ships of the border force carry the prefix « HMC » – Her Majesty`s cutter. Between May and October 2015, two of the vessels, HMC Protector and HMC Seeker, were deployed to the Mediterranean to conduct search and rescue operations. The Border Force also has a recently chartered ship called MV VOS Grace.
 In addition, there is training in initiation and remediation (personal safety training, PST) (self-defense/restraint/handcuffs/stick training). In November 2011, the Civil Liberties Committee published a report which indicated that 124,000 cases of expulsion had been postponed by the UKBA. The report stated that the cases were dumped in a « controlled archive, » a term used to hide from authorities and auditors that they were a list of lost claimants.  The border force is responsible for immigration and customs at 140 rail, air and sea ports in the United Kingdom and Western Europe, as well as thousands of small airstrips, ports and marinas. In addition to the immigration and customs powers listed below, Section 2 of the Borders Act 2007 also allows certain members of the border force to arrest someone for a crime or arrest warrant at a port, when the border guard believes that he or she could be arrested by a police officer. The authority authorizes incarceration for 3 hours until a police officer arrives. The power also applies to ports of entry in Belgium and France, where border guards work, with the border guard handing over the detainee, if necessary, to Belgian or French police officers.  Entry to Britain via the Channel Tunnel from France, Belgium or the Netherlands or by ferry from Calais and Dunkirk in France is controlled by juxtaposed immigration controls. Travellers are evacuating British passport control in France, Belgium or the Netherlands
