For what it's worth, most if not all schools directly or indirectly (subtly) discourage international students from applying in Round 3, in any given year. This is because by the time R3 results are out, admitted international students end up kinda cutting it too close for visa and other immigration formalities.
Moreover, Round 3 is ALWAYS only about rounding up the class and filling a bare minimum number of seats that are left, which invariably means that the admission rate for this round is drastically lower compared to Rounds 1 and 2.
Coming back to this year and Kellogg's extended Round 3, as long as it's not directly coming from the AdCom, it's not official that they are not going to be intentionally accepting international students. I feel that the OP who's made the comment should either reveal the source or remove the post.
Of course, if one thinks about it, and as has already been stated above, schools are scrambling to fill up the classroom in the most diverse and competitive yet realistic way possible, so it's quite understandable if any AdCom anywhere has doubts about a student actually being able to make it to the school in time, and if that bias were to somehow make its way into their decision-making.
Personally, I feel that schools are doing whatever they can to help more candidates apply, but in the end, it's still a highly selective and fair process. In fact, provisions such as applying without a GMAT score are kind of disadvantageous to those applicants who come from an over-represented pool, such as India and China, which are also known to have high average GMAT scores (which is usually a + in the application).
Again, anyone who's applying in these extended R3 rounds should hopefully assess these odds and the broader situation, and play the game only if it makes sense.
