Why would your company pay your rent?

How I can write to my personal manager a proffisional letter to get house rent payment the same like other employees in the same post of me

Again, why would your company pay your rent? If you claim other employees are getting such payments, then there has to be some corporate policy to support it. So there should be a corporate process to request it.

If you company offers a housing allowance, I would imagine it is only to employee's who negotiated such an arrangement prior to being hired. There would be a contract between the employer and the employee.

Otherwise, your employer pays for your housing in the form of wages.
