@Adelaide, Yes, I do have different paperwork requirements here..I can only guess these are the reasons why...
1. The closest USA Customs POE to me to deliver paperwork is 3 hours away.
2. The Custom Officers at this port are not there for very long..a few months at best. Training and a basic understanding of the process is limited at best.
3. Many times the Customs Officers make decisions regarding the waiver application when you drop off paperwork, (this is usually based on their own personal opinion.)
4. The volume of waiver applications is minimum compared to other places such as Pearson International, Edmonton or Calgary International. Therefore, I think paperwork is held up for a few weeks before being forwarded to Head Office.
