Frequently Asked Questions

What does an immigration lawyer in London do?

Immigration lawyers advise on visas, sponsorship, nationality, asylum, detention challenges, appeals, and judicial reviews. They represent both individuals and corporations in navigating UK immigration rules.

How long does the UK immigration process take?

Processing times vary. A standard spouse visa may take 8–12 weeks, while business sponsor licences can take 8 weeks. Appeals and judicial reviews often take several months or more depending on court timetables.

What are the most common immigration cases in London?

Spouse and partner visas, work visas under the Skilled Worker route, student visas, asylum claims, EU settlement, and nationality applications are among the most common case types.

Can immigration lawyers help with refusals?

Yes. Lawyers can prepare appeals, administrative reviews, or judicial review proceedings to challenge Home Office refusals where unlawful or unreasonable.

Do I need a lawyer for a sponsor licence?

It is strongly recommended. Sponsor compliance is complex and errors can lead to licence suspension or revocation. Corporate immigration teams ensure applications meet Home Office requirements.

Are legal aid immigration cases still funded?

Yes, but only for asylum, detention, trafficking, and certain human rights cases. Most family, work, and study visa applications are privately funded.

What is the success rate for appeals?

Appeal outcomes depend on evidence, representation, and case law. Tribunals uphold many appeals where procedural errors or unfairness occurred.

What is judicial review in immigration?

Judicial review challenges unlawful decisions by the Home Office in the Administrative Court or Upper Tribunal, often where no right of appeal exists.
