Going out for training and leaving one day in advance can be reimbursed. If you need to arrive at the site in advance for the training activities, you can apply to the organizer for reimbursement of tickets. Under normal circumstances, the organizer will review and deal with it according to the relevant regulations of the company, and those who meet the reimbursement conditions can get subsidies. However, the specific reimbursement details need to refer to the company's internal regulations. I suggest you know it clearly in advance so that you can apply for reimbursement better. Therefore, the ticket for going out for training one day in advance can be reimbursed.
