Their is a whole section on this forum just to talk about EUC's filling them out, etc. take a look there as there is a lot of good information. My first EUC last year took a bit over a month ( that is at Battle Creek, there was about a week worth of doing revisions (3) based on little things that the GL staff caught (not applicable being misspelled in one place, my name being listed slightly different on my drivers license than my GL account, changing Farm use to Personal Use in one place, etc) , the ones sense have taken about a week or so. The key is to make sure GL received everything quickly before your initial deadline, I scan everything and email it now since they require a COLOR copy/scan of the drivers license even though they still have not updated this on the web page. Get on live chat, before sending the email with the attachments, tell them you are sending it and ask for them to confirm receipt, they are VERY BAD about loosing faxes/emails then blaming their computer system/ fax machine for being out of paper.

p.s. If your physical address and mailing address that will come up in public databases does not match (such as getting mail at a PO Box) send along proof of your physical address (some people use utility bills, I have a Coast Guard Documented boat, so use my boat documentation since it has Dept of Homeland Security in big letters at the top which I hope they may think is more official looking than some local power company bill)
