US Immigration from Mexico

Response To USCIS' Request For Evidence Was Received July 1, 2021 We sent a request for initial evidence for your Form N-400, Application for Naturalization. June 23, 2021 We scheduled an interview for your Form N-400, Application for Naturalization. May 19, 2021 We received your Form N-400, Application for Naturalization, and sent you a receipt notice. July 20, 2020

This is the timeline for my peculiar case.

As background story I was born in Mexico. At age 9 my grandparents legally adopted me in hopes to be able to help me migrate to the US and finish my studies. Both my grandparents lived in the US one of them being a US citizen trough naturalization.

At age 15. I entered the US trough a land port of entry and was detained because I had no documents to grant me entry other than the fact now both of my parents (grandparents ) lived here and I wanted to be with them.

I was paroled and allowed entry, we went to court for nearly two years and was awarded permanent residency in 2015.

Fast forward give years to 2020 when I completed the 5 year permanent resident period to be able to apply for citizenship trough N-400. I applied submitted everything that is the timeline you are seeing up there. After a year of waiting I have my interview. I passed the test I passed everything but the officer tells me that I might already be a citizen because my dad was a citizen when I received my Permanent residency and I was under 18.

The sent me home and sent an RFE asking for my adoption papers and my birth certificate. It's been more than two months now and there is no update I'm sincerely growing desperate.

A lot of people told me I wasted my money with the N-400 and I should have just applied for US passport.

I want to bring my fiance to the US soon and I know another way to proof citizenship is trough US passport. Which brings me to the question can I go and apply for a US passport now trough secondary evidence? Like my dad's certificate of Naturalization

Help!!!!
