When I arrived to France with my wife and kids, no one was ready for us. I had to figure out everything by myself. Know you can count with my personal experience. I arrived without knowing a word in French and I know it could be overwhelming to manage the French language, but I speak Portuguese, Spanish, English and French so you won't have to worry who to call to help you out. Creating a business in France for foreigners is way tougher than people think and in fact, it's not only the language, the french system has improved a lot since I arrived, but it still is hard as the culture expects you do everything on your own, but that doesn't have to be so hard. I've been there in your spot before and it could be too harsh to handle, but someone has to be there to prevent it. You can hire me as a consultant when you need it, just one phone call away.

I really like to guide anyone who's willing to make it happen: start-up workers, company owners and investors who contribute to the technological development of France can apply for a French Tech Visa and residence permit. The general requirements for all categories of applicants are age of majority, citizenship of a non-EU country, no criminal record, an official source of income and valid travel documents. The process of consideration of the request and issuance of residence permit in France takes 4-6 months.
I believe we need to learn from our peers, the problem is the local culture and language doesn't make it easy for people to get it done rapidly. We are not islands and we can exchange experiences in meaningful conversation.
Even though your startup idea might not be 'successful' the whole purpose is to keep trying until you make it happen, you can pivot and in fact la France has many top resources to use.
I know that there's always room for improvement, but my experience will get you farther. I'll try to share all the knowledge as a founder,as a parent and as a colleague thtat I've collected for the past 3 years since I began this expat journey.
I just want more people to focus on the important issues of their businesses. I'll try my best to prevent you from making some of the mistakes I learned from.
