So, I have always been a guest here lurking around and learning a lot of things. I learned so much that I was able to gather all the documents(yay me!) and filed for my father. Well, about a month and half later I get an RFE that the birth certificate I submitted with my father's name on it was issued long after I was born, certificate was issued a year later, this birth certificate was easily verifiable but hey, it is the government, they always find a way to mess things up.
 
I had a long list of things that I could send to replace my "old" birth cert. I looked at all of them and went with the easiest of the things. Sworn affidavits from 2 people who knew about my birth. Although this was the easiest of the things but it was not that easy for me to get because I have no family here. Well long story short, I got everything(2 affidavits) together and mailed it off with the envelope they asked me to use and I also made sure I mailed it to the right address. I am good with addresses because I used to work at a ship and pack place.
 
My mail delivered on the 21st of November(yay me!). So, I waited and waited like y'all always advice on this forum. Nothing changed online with my case all these while, only said case was received. Didn't mention that an RFE was sent to me, also didn't mention that my evidence was received. I thought it was a glitch like I had read about a couple of times on this great forum. Well I became uneasy by December 29th. Lets just say i always feel funny when bad things are about to happen, So I placed a call to the 800 number. Although, I didn't think they would be useful but I made that call any. I explained to the lady on the phone that I wasn't feeling good about my case not updating and not knowing if they got my evidence or not. She said not to worry that they most likely got it that is has only been about 40 days and I needed to wait 60 days! I specifically told her that i could be denied before 60 days, she somewhat laughed about it and said that wont happen. That was that, until the 9th when i decided to check my case and behold, it was updated to denied. I knew 100% the cause of the denial. So I called the useless 800 number again, this time another lady, she assured me that it was prolly something else. I told her it wasn't, she said I didn't know for sure that I should wait for the mail.
 
Today, I got that mail and it said something about them giving me 87 days to respond bla bla bla and since I failed to respond, my case was denied and treated as abandoned! Say what? I have a tracking number that shows my mail delivered on the 21st of November. Well, the denial notice said something about filing to reopen my case, when I saw that I was like bingo!!! All it would cost is maybe $7 to ship a letter explaining that I never abandoned my case and then my case is then approved but to my surprise, I HAVE TO PAY ALMOST $650 TO FILE TO REOPEN MY CASE. Someone please tell me there is a way around this RIDICULOUS FEE! I did everything I was supposed to do, the post office even did their own part of the job by making sure my mail got delivered! Why do I have to lace the government's already large wallet with MY $650? I don't have $650 just laying around you know, I am struggling to understand this system! Someone please make my night and tell me I don't have to pay $650 since this was no fault of mine
