What should I expect during a home visit by an immigration officer in Thailand for a marriage-based visa?

The original poster shares that their husband received a phone call from an immigration officer requesting a home visit for an interview, raising concerns about what to expect. In the comments, others describe similar experiences, noting that home visits typically occur for those applying for extensions based on marriage to a Thai national. It is mentioned that it's common for officers to visit the applicant's residence during the first year of application, sometimes requiring neighbors to act as witnesses. There are discussions on the importance of complying with local regulations and the reasons behind increased immigration scrutiny due to abuse of the visa system by some foreigners.
