Do I need to provide my physical passport for a 90-day immigration report in Thailand?

The user is inquiring about the necessity of physically presenting their passport for a 90-day immigration report following their trip to Vietnam. They received conflicting information from a visa center, which claims that sending photos of the passport is sufficient. Comments from other users indicate that while it's usually not necessary to submit a physical passport for this report, it can often be completed quickly in person at the immigration office. There are also suggestions to avoid using services from agencies, which may charge fees, and instead take advantage of the free process.
