There are other ways to contact UKVI if you’re outside the UK.
If you’re inside the UK, who you need to contact depends on what your enquiry is about.
Change of address or legal representative
Tell UKVI if your UK address or legal representative changes:
Biometric residence permits (BRP)
Email UKVI if you’ve applied for a BRP and it hasn’t arrived or if it contains errors when you get it.
You can also report an immigration crime.
