It is important to study all relevant information well in advance before coming to the UK. This is to avoid disappointment and frustration and avoid a waste of time and money. All persons entering the UK must have a passport or other travel document valid for the UK. In addition a visa may be required. Advice on this may be obtained from British embassies, high commissions and consulates overseas. The fact that a engineer has gained the right to entry to the UK does not override the legal requirement that any engineer practising in the UK must hold appropriate registration with the GEC. Likewise registration, or eligibility to apply for registration, does not of itself convey a right to entry to the UK.
