Wrong! I‘m freelance graphic designer and have no customer contracts. I work for many customers since over 15 years without contracts and build a solid customer base in my region in Germany and beyond. Always depends on the situation and how you can explain and prove it.
Yes, a cover letter where you explain your work and the situation and a collection of your translations from some websites. Also if you have some invoices would be helpful. And if you have a website or a business profile e.g. on LinkedIn or XING, you should also include the link inside the letter. All collect in a multiple page PDF to upload as your portfolio.
I’m a freelance graphic designer with no customer contracts. I showed my portfolio of work and also a cover letter to explain the situation. They ask my for a business registration that I don’t have. Bcs as a freelance Media Designer (Sole Proprietorship) I’m not required under
German law to register a business or apply for a business license. Registration with the tax office is sufficient for carrying out my professional activities. So I provided my tax ID number. But I also had to provide all income tax evidence from the last 2 years. After all that my DTV was approved.
Bcs it only takes few hours and only costs 1900 THB. And if you have all documents already together it’s not a big thing. Border run from e.g. Koh Samui or Phangan is way out more time intensive and more costly.
Yes sorry I confused the expression! What I meant is the border bounce. For me as a German the meaning visa run or border run is the same - crossing the border and come back and get another visa. But actually my post was about the „Best advice“.
