Does my Thai wife need to report the arrival of our visitors from the UK to immigration?

When visitors arrive in Thailand on 30-day stamps, it is important for the host to report their arrival to the local immigration office using the TM30 form. This requires the host, in this case, the Thai wife, to fill out the form, make copies of the visitors' passports and entrance stamps, and submit them to the immigration office. The requirement may vary by location; for example, it is less stringent in Bangkok compared to other provinces.
