If I marry a Frenchman, does anyone know that I can immigrate with my son?

If your son is under 18, you can immigrate at the same time. If he is older than 18, your son can apply for immigration after you acquire French nationality. Specific procedures (1) The guarantor applies to the governor of the province where he is located, and at the same time delivers proof of residence, identity certificate, proof of the guarantor's residence and economic conditions, such as rent receipt, electricity and gas receipt, and proof of kinship showing the relationship between the two parties. The last kind of proof needs to be handled by the applicant in our country at the notary office of his place of residence. After being certified by the Chinese Embassy in France, it should be submitted to the French authorities. (2) After accepting the application, the Governor will hand over all the materials to the Immigration Bureau for detailed investigation. After investigation, if the guarantor is a French citizen or a foreigner with long-term residency, and his living area and economic income meet the conditions of family reunion, he can obtain an entry permit. (3) If the entry is approved, the Immigration Bureau will notify the embassy in China, and then the embassy will send a notice to the applicant and start the visa formalities. (4) After receiving the notice from the French Embassy in China, the applicant first goes to the local provincial or municipal hospital for physical examination, and the examination result report is signed by the doctor and stamped with the official seal.
