Resident Alien

I got my 10 year green card in the mail yesterday. I am very happy about it. That is finally all done. I can technically apply for citizenship this coming December 13th but I don't want to drop $1200 for it at the end of the year so I think I will wait a few years. I price goes up every year but I am hoping to be in better financial standing in a few years where dropping that much money wont hurt as much. So now I can travel to other places without any difficulty but I wont be traveling for awhile.

On a side note does anyone have any good ideas for brown bagging it. I have been researching money saving tips and apparently brown bagging it to work is one of the main ones people don't see. I was thinking about it and even if you only spent 5 dollars a day on lunch at work (most people spend a lot more than that at restuarants) you are spending $100 a month on just one person just for lunch. So there is a possibility for savings there. So any good ideas. I know if I do the same thing for even a week straight Daniel won't eat it and it will just be a waste of food and effort.
Thanks
