Hi, I just moved out of my place and I am not sure what to do with the change of address form. I am currently spending a few weeks overseas and I will be spending some time with a friend when I return until I find a new job and move to a more permanent location. Since there is still someone living at my old address who can get my mail, should I return and am physically at the new address to file the form or do it now? Do you have any advice? Thanks.
