In Phnom Pen getting a new tourist visa. 3 days to get it, not less even paying extra money, ticket of leaving Thailand before 3 months, dont ask for ticket getting in Thailand, and actual bank account statement.
I hope it helps.
TLDR : Answer Summary
To obtain a tourist visa in Phnom Penh for Thailand, applicants should expect a 3-day processing time, regardless of whether they pay extra for expedited service. They will need to provide a ticket confirming departure from Thailand within three months, an actual bank account statement demonstrating sufficient funds, and there is no requirement to show a ticket for entry into Thailand.
