Moving to France, auto-entrepreneur contracted by US LLC

Bonjour Valerie,

Apologies for the long question, please let me know if a direct email or your advice call service is a better venue.

I am a US citizen and have received an Entrepreneur / Profession Liberal visa (after waiting 7 months for it…).  I arrive in Paris in just a few weeks!

I currently operate a US limited company through which I provide software development services.  I am paid a combination of salary and dividends/withdrawals.  My currently plan is to continue to bill my clients through the US company, set up as an auto-entrepreneur in France, and have my US company pay the French company in lieu of my salary.  As such I will continue to receive dividends but no salary from the US company.  I will also find and engage additional clients through the French company, which will net less than the 70KE annual AE limit.

I have a few questions which are variations on others I have seen here -

1. Is this legal and your recommended way to structure the business?
2. Will I be taxed in France on the dividend income from the US company or only in the US?  And I assume the business corporate income would remain taxed only in the US?
3. Is it allowed to manage the US company while resident in France or would I need to bring on a domestic manager?
4. I will be setting up the Auto-Entrepreneur business in France (interested in your services!) shortly after arriving - is there a deadline for having that business registered?  Do I need an established personal address before registering?  I read somewhere that it needed to be within 15 days of arrival in France, but that sounds insane.
5. Can you recommend an English-speaking French accountant with experience dealing with foreign businesses?  And would you recommend I engage an accountant now or at tax time?
6. I want to make sure I am registered correctly as a French resident on my Visa de Long-Sejour as well (registering with OFI, registering the business, opening personal/business bank accounts, registering at the address of the flat I am renting, etc), do you know anyone who provides relocation advice for expats?

Thank you for your time and for this wonderful wealth of information, it is a gem in the haystack of the internet!

Merci bien d’avance!
