The essential difference between the application for joining the party and the letter of joining the party

Many people may think that there is a difference between the application for joining the party and the letter of joining the party. I feel that the difference between the two is not big, but in fact, the application for joining the party is essentially different from the letter of joining the party. The application for joining the party is submitted by the applicant to the party organization and the written materials for joining the party. The party's voluntary letter is submitted to the applicant by the party organization. The application for joining the party only indicates the applicant's personal attitude, and filling in the party's voluntary letter marks the organization's attitude towards the applicant. The application for joining the party is entirely voluntarily written by the individual, and the admission letter to the party must record the entire party joining process of the party. It is filled out by the applicant, the introducer, the interviewer and the party organization according to the regulations and requirements. The application for joining the party is more flexible in writing, and the admission letter to the party must be filled in strictly in accordance with the prescribed columns, and it should be noted that the content of the application for joining the party cannot be copied into the content of the individual "joining the party". "Participating in the party" should rewrite the understanding of the party based on his own growth process and the process of ideological change, why he should join the party and his future plans and determination.
