Is the refusal rate of French visas high? What can I do to avoid being refused a visa?

France still has a certain chance of refusing a visa, but whether the visa is approved depends on all aspects of the applicant, including travel records, assets, marital status, authenticity of work and purpose of visit, and sensitivity of the domicile. So basically, most people who are refused visas are lacking in these aspects.

Of course, some people may do well in all aspects, but their personal data is too weak, so you can consider using external forces to improve the signing rate.

Some people may have good personal information, but there are omissions in the preparation materials, so they should check for missing information and improve the information before submitting it.
