French administration works in a strict order: the visa unlocks the bank, the bank unlocks health cover, and one missed step in week one can stall everything that follows.
The first 30 days in France are when a relocating executive is busiest at work and most exposed to administrative friction. This checklist splits the month into four weeks and separates what HR should handle from what only the assignee can do, so nothing falls between the two.
French procedures depend on each other. A proof of address is needed for the bank; a bank account (and its RIB, the account details sheet) is needed for salary, health reimbursements and most contracts; a social security number unlocks the carte Vitale. Getting the order right saves weeks.

| CPAM application, primary doctor | RIB, birth certificate, contract | 4 |
| Transport reimbursement, licence check | School follow-up, licence exchange plan | Visa validation date |
Waiting too long to validate the visa. Three months sounds generous, but the validation certificate is needed for other steps. Do it in the first days.
Arriving without a full birth certificate. The CPAM file cannot move without one, and ordering it from abroad can take weeks.
Using a hotel or holiday rental as an address. Banks and administrations want a residential proof of address. A lease from day one avoids a circular wait.
Keeping only a foreign phone number. Security codes for banks and public services often go by SMS to French numbers.
Forgetting the driving licence clock. The one-year deadline starts with the visa validation, not with the day the assignee buys a car.
The fastest relocations share the work clearly. HR and the mobility partner prepare documents, book appointments and chase follow-ups. The assignee signs, attends and validates what only they can do. Writing that split down on day one avoids the most common delay of all: each side assuming the other has done it.
Some steps take longer than a month. Plan to follow up on:
Le Mendèlle handles corporate housing and administrative onboarding (health cover, driving licence, tax return) through a single point of contact, so the assignee's first month is spent on the job. See also why settling-in services are the missing link in global mobility.
What is the deadline to validate a French long-stay visa?
Three months after arrival. After that, the visa no longer counts as a residence permit.
Can an executive open a French bank account before arriving?
Some banks offer non-resident accounts, but most will ask for a French address before the account is fully active.
How long does it take to get a French social security number?
It varies by local office. A provisional number is usually issued first; keep paper treatment forms (feuilles de soins) to claim later.
Does the employer pay for public transport?
Yes. Employers must reimburse 50% of public transport passes used to commute.
What documents count as proof of address?
Usually a utility or internet bill, a lease with a recent rent receipt, or a host certificate, generally less than three months old.
