Dual citizenship

I have dual citizenship. The USCIS is asking for a letter of renunciation to my country of birth nationality to process my I-485 application. I do not have a letter of renunciation because it was not necessary to acquire my 2nd citizenship. Is dual citizenship a restriction to approve my I-485 application?

I-485 & dual citizenship

The Request For Evidence letter I received says: "Submit a copy of your birth certificate showing your parantage, which has been registered with the proper civil authorities of the country of you birth (Panama). The document that you submitted was a late registration in Mexico. According to Panamanian Citizenship Laws, if you were born in Panama with one Panamanian parent you are a citizen of Panama. Did you voluntary submit a letter of renunciation? Could you please send a copy of that letter?".

What could the letter of renunciation be needed for? Mexico and Panama both accept dual nationality and do not require renunciation to other nationalities. Thanks for the interest and help.

The issue is not that you are dual citizen, but the fact that you submitted incomplete/conflicting information on your citizenship.

You neglected to send them the Panamanian birth certificate.
They don't know based on all your Mexican documentation whether you renounced the Panamanian nationality or not. That's why the phrased it in the form of a question. If you did renounced, they want that documentation. If you didn't, tell them that.
