Hey guys. I've been invited to apply for permanent residency in Canada. However, I recently finalized and acquired German Citizenship by option thru my dad but was born in Argentina. I obviously want to use my German passport as my primary citizenship but am I able to chose which one I want for primary citizenship though? Or can I use both interchangibly when traveling to Canada ? I prefer the German since it's a hassle free passport and can get me to lots of countries visa free. I appreciate your comments .
