84 nations have qualified for PyeongChang 2018. I have not included the Cayman Islands as they won't compete and included Ecuador who will make their debut.
The following should qualify (all have athletes meeting part of the standard/good enough to qualify):
India (cross-country skiing)
Philippines (alpine skiing)
Hong Kong (alpine skiing)
Moldova (cross-country skiing)
Venezuela (alpine skiing)
Chinese Taipei (speed skating).
= 90 Nations
The following have athletes just outside qualification, I rate their chances as good.
Nigeria (women's bobsled)
The following have athletes just outside qualification, I rate their chances as not that great
Algeria (alpine skiing/snowboard)
Barbados (freestyle skiing)
Costa Rica (freestyle skiing)
Nepal (cross country skiing, their athlete needs really good results to have any chance).
Paraguay (freestyle skiing)
Senegal (alpine skiing)
Trinidad and Tobago (cross country skiing, their athlete needs really good results to have any chance).
Almost no chance to qualify, but have athlete(s) competing to qualify:
Dominican Republic (hard to comment, as this athlete has yet to compete).
Almost no chance to qualify, but have athlete(s) competing to qualify, but have a small glimmer of hope through reallocation in figure skating:
Singapore (their female skater is two spots out of reallocation, and if this were 2010 she would qualify as there were 2 reallocations back then).
