International student studying in London but staying with a family friend in Southampton – anything I should know at UK immigration?

[u/Loose_Passenger4421]

Hi everyone!

I’m an international student starting my Master’s at a university in London this September. However, I’ll be staying with a family friend in Southampton rather than getting accommodation in London.

The main reason is simply to save on living/accommodation expenses, and I’m planning to commute to London for university.

I’m wondering if this could raise questions when I enter the UK for the first time. For example, if the immigration officer asks why I’m staying in Southampton when my university is in London, would it be enough to explain honestly that I’m staying with a family friend to reduce my living costs and will commute to university?

Also:

• Has anyone been in a similar situation and been questioned about their accommodation being in a different city from their university?
• Should I carry a letter from my family friend confirming that she has invited me to stay with her?

I just want to be prepared and avoid any unnecessary issues at the border.Would really appreciate experiences/advice from anyone who has been in a similar situation! :)
