Paraguay citizenship

I wish. To obtain citizenship in Paraguay, my father was born there and still alive unfortunately he is not of any help in this matter for various reasons. I'm looking for advice

If you haven't contacted the Parayguayan embassy where you are now, I'd suggest you do so.  If you are in Paraguay contact Migraciones, click on Contacto on the menu bar of the link above.
