First of all, I'm a U.S. citizen and I was living in Belgium for a year with my boyfriend (Belgian) as my sponsor. We had a big falling out and I surrendered my resident i.d. card before I left (for multiple reasons I won't go into now).
We are still planning on having me visiting Belgium and the rest of the Schengen Area maybe some time later this year.
I am aware of the 90 days within 180 rule for the area. Though, I am thinking that the number that lies after the date on my passport stamp states how many days I have left in the area?
I initially visited for just short of 90 days and came back after 3 months. When I entered in April 2012 it said 84. As I was leaving April this year, I was given a stamp with a 75 after the date. Does that mean I have 75 days left next time I come into the area? How could I tell when my 180 days reset in this case?
I just want to make sure that we can plan another trip without getting into immigration trouble.
