the guy is asking advice reference his DYV. You commented that the only way he could leave and re-enter would be to use an agent. I'm simply disagreeing in part. That's all 🤷♂️
I understand, that's why I'm saying that if visa exempt, with history, then definitely use an agent. But if that person has a visa, a DTV as in this thread, then there is no need for an agent
You don't need a multiple re entry tourist visa if you are only staying 90 days, depending on your passport. You should get 60 days with no visa, then extend for 30 days at rhe local immigration office
