I am an Indonesian passport holder. I have a multiple entry Schengen visa, duration of stay: 90 days, valid for 2 years, issued by the Dutch embassy on November 2014 (valid until November 2016). I will be staying in the Netherlands for 90 days starting on 1 January 2015 and ending on 31 March 2015.
My question is: can I spend 90 days in Romania/Croatia/Serbia/Bulgaria for 90 days starting from 1 April 2015 until 30 June 2015 using my existing Schengen visa? I will then fly back to the Netherlands on 1 July 2015 until 30 September 2015.
My aim is to stay in Europe for one whole year in 2015:
- 90 days in the Netherlands (January, February and March)
- 90 days in either Romania or Croatia (April, May and June)
- 90 days in the Netherlands again (July, August and September)
- 90 days in either Serbia or Bulgaria (October, November and December)
