I travel internationally. These arcane rules also do not affect me.

Me: Lifelong, native-born citizen of a western nation. 1 or 2 international trips of less than 2 weeks each year.

Author: Immigrant to his country of residence. Applying or soon to apply for citizenship or permanent residency. Has taken multiple, lengthy international trips and also appears to have had immigration status in different countries .

Conclusion: If you are more like me than the author then international travel will not require navigation of arcane and contradictory rules.
