Need info about Belgium Residence permit
I have a Belgium work permit valid till 30 June 2015. Also I have a valid schengen visa for a year. My wife and daughter have schengen visa valid for 180 days till 5th March 2015. Now if they go back to India after 90 days can they come to Belgium again before 5th March or do they need to get the schengen visa extended before they can enter in Belgium again.
If I get the Belgian residence permit for my wife and daughter will they be able to come back after 90 days.
I searched on internet but could not find any link giving info about residence permit and schengen visa. So Appreciate if someone can provide some links about this.
