A Prime Minister's Office regulation on deportation took effect on Friday 28 August. Authorities can quickly deport foreigners who act aggressively, disrespect Thai culture, or break the law, and those working or running businesses illegally are targeted. Offenders get visas revoked and a permanent re-entry ban. For a Thai SME, the practical point is to check that any foreign staff, partners or contractors have valid work permits and that their visas match their actual role, since illegal work now carries strict enforcement. Tourism-facing businesses should also expect tighter tourist police coordination. The article gives no fees, penalties for employers, or detailed criteria.
