Visa Renewal/Extension:
Apply before current visa expires. For work visas, ensure continued sponsorship and salary compliance .
5. Cultural and Practical Tips

Accommodation:
Research areas using [police.uk] to check local crime rates. Avoid upfront rent payments without viewing properties .
Emergency Contacts:
Save 999 (emergency) and 101 (non-emergency police). Contact the Chinese Embassy (+44-) for consular assistance .
