Can teachers find that they do not meet the recruitment requirements after joining the job through letters and visits?

Letters and visits have been accepted or are being handled, and the complainant once again puts forward the same letters and visits to the higher authorities of the accepting and handling organs within the prescribed time limit, and the higher authorities refuse to accept them.
