Help on DACA renewal

Now my DACA expires on March 5,2015. And well my question is to I send out my applications exactly 120 days from that day? I used a DACA renewal calculator that i found on a website and it tells me to

Submit my DACA renewal application AFTER this date: October 6,2014
Submit my DACA renewal application BEFORE this date: November 5,2014

You may want to send it with 150 days before expiration , based on my calculation send it in oct 16 2014. Give yourself the best chance and submit it 150 days exactly. Some people in here are getting approved faster than others and some are reaching the 120 days without hearing anything from uscis. I submitted mine with 138 days before expiration, i wish i had those extra 12 days just in case , apparently renewal is not as smooth. Make sure everything is signed properly , copy of ead front and back , passport photos, your 765, 765 ws, and 821d. Good luck

And i submitted mine 147 days before expiration...

I got a question if I filed it myself do I need to fill out the preparer and interpreter part?

No....

Just the requestor Part 5

Alright. Thanks hope it makes it through.
