Thanks,

Changing my residence to UK is an option, but I don't really know which are the requisites for being resident. I'm currently EU citizen and I think that being so I only have to ask for the residence in London.

I think that being hired from UK grants me access to UK's Social Security system and to public health & care. Can you confirm this?

Which benefits will I have if I decide to change my official residence to London?

Thanks in advance.
