Hello, I am currently applying for DTV under soft power option in Poland. I got a letter of appointment from my dentist.

I got 3 questions :

About accommodation do i need to provide anything ? I don’t know if i should put the rental agreement of my villa (Started in June 2023) or book a refusable hotel through booking

About date of leaving what do you put inside ?

Last question, do I need to make a professional photography or can I use one made with my iPhone ? (I used my iPhone for my METV)

I am selling my house and moving to Thailand. I am almost retired and live off passive income but not 50 yet so I need to do the soft power option of the DTV. Does anyone know how to get a letter from a Muay Thai gym . I’m active and think I would enjoy doing that but have no idea how I go about getting an acceptance letter and what is needed on it . Thanks !
