Naturalisation and citizenship in Guatemala

You do not have to give up your former nationality. That I know, even though I have a legal residence, not a naturalization. That is, I am legally allowed to work here, I do not have to travel out of the country to renew a visa, and so on.  As far as I am concerned, the only advantages I would have as a citizen, were I to become one, is that there are a great many European and Asian scholarships available for Guatemalan citizens that go unclaimed every year, for undergrad to post-graduate courses and degrees and all sort of educational opportunities. Also, I would be able to vote in this country --although I think the US discourages people with dual citizenship from voting in other countries-- but I am not really interested in that.  In other words, I never went "all the way" into a Guatemalan citizenship, just remained a legal resident. I would suggest that anybody wanting to become a citizen in Guatemala and hold dual citizenship go to an immigration lawyer.
