To apply for Permanent Residence, your visa need to have 3 or longer years.
In the future, even if you want to apply for PR, if your visa remains 1 year, you can’t apply for it.
I hear a lot from you:
“Why do I always get one year only?”
“It is very bothersome to renew my visa every year.”
As a preparation to apply for PR, your priority is to get longer period of visa.
Of course, the final decider is Immigration Bureau.
I don’t have such a power, but I can judge if you have a chance to get it or not.
After checking your answers, if I think you have a chance, I will tell you my fee and tell you what to do.
