You can contact a suitable tour operator, provide the employee with the necessary documents if you do not have time to independently apply for a visa to Mexico. Agents will do everything for you, only for services you have to pay. Here it is worth discussing the details in advance, for example, whether you will return the amount paid to you if the consulate refuses to receive a visa to you. After all, it may be so — you will collect all the documents, provide agents, but in the end you will not receive a visa. It is worth noting that the consulate does not announce the reasons for the refusal.
