SAT Monterrey - 64000 Monterrey

Terrible service, they can't cope with their procedures even if you come by appointment, outside the office there is a lack of signage and information, there are many people trained and there is no one to clear up your doubts until you arrive at the entrance. (I recommend offering you the line if you have any questions) Once inside you have to wait about 4 hours (I lasted 4:30hrs) for them to pass you and while you're waiting you're sitting with more than 100 people and with only one fan, the heat is unbearable I don't know if the weather there is not enough or it does not work but how sad that they are those who are in charge of collecting the money and those who use it the least for the benefit of the consumer.

By appointment the service time is very fast. They allow you to enter a little earlier than the scheduled time. There are a lot of people at reception. They serve you quickly. Many care cubicles. They let you use their computers and printers. Excellent service. Congratulations!

I did the process of my signature and it was very fast, I came in at 9:05 (time of my appointment) and by 9:40 I had already left. The receptionists, very friendly staff, answered all my questions and were very clear. You have to consider that to go to carry out any procedure you have to make an appointment on the SAT page, otherwise even if you arrive very early you will NOT be attended to unless: 1. You are a senior citizen and you are one of the first 40 to arrive and they will assign you a shift, shifts are given at 8 am, so arrive early (seniors) 2. You require your tax certificate, there is an exclusive line that goes very fast and they give everyone their certificate, I don't know what they want but I understand that only the INE. Considerations: You are going to have to wait, preferably bring an umbrella because the sun shines directly, there are no chairs to sit or waiting rooms outside, only inside the branch. Making an appointment can be a problem if you are not constantly looking for an appointment, I recommend going to twitter and activating the notifications of the accounts @citassat, @availabilitysat among others, which notify you when appointment spaces are opened on the SAT and it is much faster that way than the virtual queue.
