Entry clearance is the procedure used by Entry Clearance Officers (ECOs) at British missions overseas to check, before a person arrives in the UK, if that person qualifies under the Immigration Rules for entry to the UK.
In some cases entry clearance is mandatory, in others it is optional. In all cases, the authority to admit someone to the UK ultimately rests with the Immigration Officer (IO) at the port of entry.
If your application for entry clearance is refused by the Entry Clearance Officer (ECO), you may have one of the follwoing options available to you to challenge the refusal depending on type of the application you submitted:
- Appeal to the First Tier Tribunal (Entry Clearance Appeal)
- Administrative Review
- Pre Action Protocol
- Judicial Review
