My old passport has a valid Pakistan visa, but the passport date is less than half a year. I am applying for a new passport. Do I need a visa for my new passport

I suggest that when you apply for a new passport, you should also apply for a new passport, that is, indicate on the new passport that it was renewed according to XXX passport, so that the old and new passports will be related. According to international practice, the old and new passports are used together, and the visa on the old passport is still valid. Generally speaking, the validity period of the visa on the old passport will not exceed the validity period of the passport. Therefore, before the visa expires, it is recommended to apply for or renew the visa with a new passport.
