Tier 2 ICT visa extension for dependents

[UMSP]

Hi, I am going to apply for my tier 2 ICT visa extension by next week, but my family (dependents) of my current visa are in India now, they cannot travel here for extension process, can they attend the Visa office over there for extension processing while I do it here at UK ?

Your dependents can only apply for extension while in the UK.
You will need to process your extension first and your dependents will then need to apply for a fresh entry clearance from India
