Bryanlibin, my condolences about your loss! And as someone who has aging parents in another country (alone) and trying to bring them here (4 year of waiting on 1st stage of sponsorship :-( ) I can empahsize what you - and your mom now - are going through...Hope it all resolves successfully for you...
I hope I am not being insensitive (really have no intention to be! ) - but maybe you can post what the embassy replies once you hear from them....Just wondering what their process is in such cases....(wish none of us ever has to go through such an experience ...)
Good luck again!
