TIER 2 ICT Dependent extension

[Srija]

Hi All,

Thanks for reading this.

My husband recently got ILR (via 5 year stay with Tier 2 ICT visa) and i am still a TIER 2 ICT dependent. My Visa expires in next year June. It would be great if some one can answer my below queries,

• 1) I understand from other's query that i can stay till my current t2ICT visa expires. But my question is 'Can i extend my visa now?'
  
  2) Should i extend my visa as PBS dependent? Please guide me to right application form?
  
  3) If i extend my visa a PBS dependent as it is now then should i need to pay NHS extra charge?
  
  4) Should i take English language test for my visa extension?
  
  5) Approximately, how much it is going to cost for my next extension?

Thanks a lot
