Hi, good morning...my overstay fine is 18k and...

We would like to inform you that as long as the value of the fine related to overstaying is reduced, you must pay it within the specified time and there is no deadline for payment in this matter
However, the General Administration of Residency and Foreigners Affairs may exclude giving an additional period of time if there are convincing reasons for this
Therefore, we advise you to submit a request to postpone the payment of the fine, stating all the reasons for which the request may be accepted

We previously indicated to you that you must pay the fine on time, which is tomorrow
But if you are unable to pay, you can submit an application to postpone payment to the Immigration Department, and the possibility for the approval of the application is very low
