There are, in fact, many stages of the immigration process at which the right to appeal may be granted. If you believe that an incorrect decision was made, or if you have some new information that would further support your case, then lodging an appeal could mean that an earlier decision is overturned, therefore allowing you to enter and live in the country. You should utilise the help of qualified legal professionals with experience in the immigration field in order to ensure the best chance of success.
There are a number of stages during the application process, when you can appeal the decision made regarding your entry into, or remaining within the country. An entry clearance appeal enables an appeal against the refusal by the entry clearance officer to allow entry into the country. For those inside the UK, and applying for an extension to stay, an appeal is also made to the First Tier Tribunal. There are time limits regarding when you are able to submit an appeal, and if you miss these limits, then it makes making a fresh application, or not being able to continue with the application process.
As well as appeals, a judicial review may be considered a form of appeal. Rather than questioning the actual outcome of the immigration case, however, these question the legality of the decision. They are used when you, or your legal team, believe that a decision is unlawful rather than simply inaccurate, and are often considered a last resort.
Immigration cases are highly emotive, and they can impact the applicant as well as their friends and family. With so much riding on the decision of the court and the UKBA, it is important that you have adequate legal representation, in order to help ensure that you have the best case possible, and the greatest chance of a successful application or appeal.
It may not be too late to be allowed entry into the country, or be allowed to stay, even if a friend or loved one has been detained. It may be possible to appeal or submit an application for judicial review, but it is vital that you have a solid legal team working on your behalf to help achieve the best results.
