Thanks Rusty...but under the old rules before 06th April 2012 which my wife visa included..those under Domestic Worker visa can get their dependent partner or child under 18 yrs old to join with them provided that the requirements are met. The rules you have mentioned above are the rule on ODW visa implemented by Home Office to those applied after 06 April 2012..and as per those applied or already in the UK under ODW route are not affected by this new rule and should be treated as per the old rule.
