How can I obtain a police clearance document for a Non-Immigrant B visa quickly while in Laos?

The user is facing challenges obtaining a non-immigrant B visa due to lacking a police clearance document and is currently in Laos with limited time to acquire this document. Users in the comments suggest that obtaining the document within one hour is unlikely, typically requiring a queue followed by a two-week wait for processing. Recommendations include contacting their embassy, going back to Bangkok, considering a single-entry tourist visa as an alternative while waiting for the police report, and sharing personal experiences about varying requirements in different locations.
