I am preparing to apply for a DTV visa for medical purposes. I have a few questions to ask you:

1. Is there anyone who has successfully applied for a DTV visa for medical purposes? Is there anything I need to pay attention to?

2. In the first item of Support Document, Biodata page of Passport or Travel Document, do I only need to submit the first page of my passport? Or all pages of my passport?

3. In the fifth item, Proof of confirmation to attend the activity or letter of appointment from hospital/medical center, do I need other documents in addition to the doctor's certificate from the hospital and the appointment form issued by the doctor?

4. In the option of Employment Details, I chose self-employment with an annual income of less than US$20,000. Is this option okay?
