Today I got the EC.



I have this in my pasport:
"UK ENTRY CLEARANCE
Type:VISA HIGHLY SKILLED MIGRANT PROGRAMME- HO Ref: 0(missing-not enough space)
My unmarried partner( I applied together with him) got the same visa but with this:
"Type: VISA TO ACC PARTNER - HO Ref: 0121XX"
I would like to know If he will be able to work and to be empoloyed freely as an ACC Partner visa?
What exactly means that "ACC"?

Thank you very much!
