One good thing about having a certified visa agent file your application documents is that the applicant does not have to wait in a long line to file and to receive the residence card since I am allowed to make a reservation beforehand. There happened to be a much longer line of people than usual at the Immigration Bureau today, and I assumed they had to wait for 3-4 hours to file. I quite often leave the Immigration Bureau in less than 30 minutes after arriving there, but it took barely 50 minutes to get everything done today.
The same thing was happening at the convenience store on the first floor since quite a few people had to buy revenue stamps to receive their new residence card. I cannot make a reservation for this, so will buy revenue stamps beforehand to receive new residence cards from the next time.
