DTI permit

Dear, I don’t think you need a DTI permit. As for your situation, you can apply for a tourist L type. And your fiance brother can issue an invitation letter to you. With the invitation letter, you just need to provide other required documents such as your passport and its photocopy, a recent bareheaded color photo, as well as the application form. But if it is the first time you apply for PRC entry permit, you also need to provide your financial supporting proof such as income certificate or bank statement etc.
