I wish to move from WA (my sponsored state) within the 2 years that i am suppose to stay there. I sent WA immigration an email saying that i wish to change state and they responded by saying " please send your reference number so we can helpyou on this matter". I have a valid excuse and i am not lying but i am a little worried they might just say NO! Then what do i do!??! I was thinking about not telling them but i would rather be up front with them. What do you guys think? has any one wrote to your state and asked to leave or have you just left the state and moved to another without saying anything.
