Who else is going to write the letter? I tried under the remote worker category, and I was denied, I own my own business and do everything online, I provided every document I could possibly think of, they even called me and told me what documents to give them at the embassy, I followed all the instructions, Wrote my own letter stating I was allowed to/work remotely, which is what I’ve always done, anyway it was declined, then they called me and said why don’t you apply under the soft power activities category, I said what a great idea, thank them very much for calling me, applied that very dayunder soft power activities, got a letter on letterhead from my Dentist that she also signed, I was approved the next day, my wife was also approved the next day after that
