I will be visiting the US and will be taking my work laptop with a US keyboard layout. In the past, I have had trouble reentering the UK because the laptop looked like it was bought in the US and I was challenged at customs. Is it possible to obtain paperwork to make the reentry easier?
The original invoice or receipt showing that you or your company purchased it in the UK would be best. This way you can prove the laptop is personal belongings you originally owned in the UK and thus exempt from duty and Import VAT.
