For the other countries (e.g., China, India), visa processing is usually smooth and with a predictable (positive) outcome.

Lessons learned from other conferences, e.g., ACM MobiHoc 2016, tell that little visa issues arise for travelers attending a conference in Germany. There are no “blacklisted” countries.
