You have selected the following level:
Add a new UK LTD company by shares.
You act as sole shareholder and director and open a bank account in the same name as your Series LLC.
Afterwards you sell your shares to the Series LLC.
The result is your UK LTD company has a 100 % anonymous shareholder.
You will be able to apply for a bank account much easier than for a "normal" Series LLC.
