I am planning to apply for my DTV in Germany (Frankfurt)

I am the 50% Owner/CEO of the company(GmbH).

I have my employment contract from 2004 and my added Remote work permission from 2020 uploaded to the system. All on company letterhead stating HRB number and Tax number .

All the other items passport,

Photo , current location, financial proof etc have been uploaded as well.

Anything I might have missed?

Or an other suggestions?

Thanks in advance.

Or

Not really the right place here but maybe someone knows, Google wasn't really helpful:

My fiancee and I will be flying from Bangkok to Germany next week. It's her first time out of Thailand. We're well prepared but I'm unsure about what documents the pass control at the airport in Germany might want to see. We have the letter of guarantee, invitation letter from guarantee and from local government, valid visa, "proof of relationship"(printed pictures from the pas three years), vaccine pass, pcr test results. Anything else you can think of? I don't want to risk any problems. Thanks a lot!
