When we came in for the first time on our Tier 2 ICT this past September, the IA was....um.....a jerk, honestly. She had no questions for me (the dependent), but was grilling my husband - who did he work for, how could we prove to her that he still worked for them (she wanted to see business cards, emails, etc), where was his contract (he doesn't have one, as he is technically a US employee), and lots of other questions. She left and went back in the room for about 10-15 mins, then finally came out, asked a few additional questions, and let us go. So, IME, the Tier 2 dependent is easy (they didn't even ask me how we were related), the Tier 2 might have a few more questions. However, every single other time we have come back in the UK, the IO's have been super friendly, polite and everything has been quick. So, we may have just had a bad experience to start. Good luck!
