If you find your self in the next couple of months have to renew yours? Keep in mind that you get one free renewal for your current I-171H. You must send in your request to have a free onetime renal before your current one expires. This is what I am going to do.
Ok with the wait extending out so long there is a good chance that our new I-171H will be expired or is going to expire with in 6 months of getting a referral. Your agency will ask you to redo your second one if they aren’t sure it will still be good buy the time you get a referral. So this is what I am doing. To make the most of my one-time free renewal I sent in our I-600A two week before our I-171H was about to expire with all the backup docs, and there signature Required. They will send me a letter that states my I-600A that I have filed with them is good for one year. When I get a finger print appointment I will ask for a latter date. That will take them a couple more months to get me one. Then when I do have a home study update and get new fingerprints it will be. Another couple of months before they get me a new I-171H that will be good for the next 18 months from the time they issue it.
Doing it this way I will be able to have a I-171H that will be good the 26 months instead of expiring in 18. Hopefully that will be enough time to get a referral we are only 8 calendar mounts away from our LID of 7-22-2006 but that could easily = 24 more months of waiting.
