I asked the orgranisers of the chennai provincial and they said that it is “not a regional or any qualifying contest, and has only one round”. I guess that means that they don’t have slots for finals.
@aneesh2312 this link pretty much explains everything about the regionals of 2017: ACM ICPC 2017
However the rules may change, you can check the ICPC 2016 page to compare with 2017.
If you want to know something that’s not on these pages ask, and I’ll try to answer if I can
EDIT: …since I was a participant (forgot to mention)
All details for ACM-ICPC 2017-18 can be found here.
There will be 5 places where regionals will be there and most probably, unlike the last year a final site has been removed so now selected teams from all 5 sites will go to World Finals.
Teams participating in xProvisionals/Nationals will not advance to World finals. Here I am quoting actual lines from Asia Director ACM-ICPC blog ,
Team registration for provincial and national contests must be done in ICPC web site. The Provincial/Multi-provincial/Invitational/National contests are independent of Asia Regional Contests. No team will be selected and advanced to World Finals from these Contests
