REMINDER
Tomorrow is the last day you can visit an immigration office until 17th April. If you need an extension or other service prior to the 17th then go tomorrow. Many offices will be very busy because of the upcoming closures.
Many offices will be absolutely manic on the 17th because of the 5 day closure. Also bear in mind that services can take extra time just purely because of the volume of people. It’s not the staffs fault that so many decide to show up at the same time.
If you can avoid going in tomorrow or the 17th then it’s probably wise to do so.
