Leaving Vietnam later than your visa expiration date is considered an overstay and is a violation of Vietnamese immigration laws. If you overstay, you may face fines, penalties, or other legal consequences. The penalty for overstaying a visa in Vietnam depends on the length of the overstay. For instance, if you overstay by one to three days, the fine might be relatively small. However, longer overstays could result in higher fines, potential deportation, and a ban on re-entering Vietnam for a certain period. Thus, it is critical to follow the validity of your visa.
If you realize that you cannot leave Vietnam before your visa expires, you should take action immediately. You may apply for a visa extension or a visa renewal as soon as possible before your visa expires. This process requires a visa extension form, your passport, the status of your current visa, and an additional service fee.
If your overstay was caused by an emergency or unforeseen event, you must request assistance immediately. However, this is not guaranteed, so do not rely on it as a solution. If you intend to stay in Vietnam for an extended time, make plans to obtain the necessary visa or extension to ensure a legal stay.
