If you want just a bank account for US LLC, Mercury is an option. But not for long. They are openning too many accountf for almost any money launderers from a third world countries, who owns US LLC. It will take not a long time to have them closed and all money frozen.
As your profit is reasonable, you should think about making a more sophisticated structure.
I will explain just the best one for you as resident of Belgium.
1. Obtain a residence permit in a country with a territorial taxation.
2. Form a foundation in some country with a territorial taxation. You will be a foundation administrator.
3. Form a company in a country with a territorial taxation - Your foundation will be a shareholder and director, also.
4. Make This foundation and you a members of US LLC.
5. Obtain EIN for US LLC and ITIN for you.
6. Travel to the USA and open bank account in a standard bank. The most of US banks are willing to open abnk accounts for US LLCs formed in their state. They will also require som more paperwork if you are a foreigner. But Belgium passport will make them feel secure.
Why is this structure good?
US LLC will have a 2 partners. Your foreign company and you. You will be a member having just a 1 % of interest. Your foreign company will have 99 % of interest in US LLC.
USA is not reporting under CRS.
US LLC will be manager by foreign corporation, which is owned and directed by foreign foundation. Foundation does not have UBO:
For all tah authorities, this structure is very hard to go through. Especially, when in all documents will be stated you as a foreign resident..
