Can my friend from Italy extend his expired Non-Immigrant visa for 30 days at the embassy?

The conversation clarifies that a Non-Immigrant visa cannot be extended for just 30 days at the embassy. The only option for extending a Non-Immigrant visa is for one year if financial requirements are met, or in cases of marriage to a Thai national or having Thai children, where a family visit extension of 60 days may be requested. It's emphasized that the individual is currently overstaying their visa, which can lead to potential legal issues.
