My Scenario :
My Current Visa Category : Tier 1(General) - valid till September 2015 in (2+3 year scheme)
Spouse - PBS Dependent visa issue date : Jan 2013 (In UK but previously on T1 (PSW) & T4)
Children - PBS Dependent visa issue date : May 2013
My ILR Due Date : September 2015
From one of my previous post - I got good information(by vinny) that I can only apply for PBS dependent for my wife and child until they complete 5 years in UK under dependent visa.
QUERY :
Question 1 : Could I apply for their visas from India ?
Because Tier 1 Dependent cost in UK : £1607 (postal) and £2007 (in-Person) whilst in India it is £874 only
Question 2 : I would be moving from Tier 1(General) to ILR before they start making the application. Then would it be possible for them to apply under PBS dependent from home country ?
Would there be any issues taking this route because this would save me £2000 but again like everyone I dont want to complicate the matter just for saving few quids

Thanks for the kind help in advance.
Regards,
Aj
