How would a foreigner go about showing their japanese company that they are there to stay for long term? There seems to be a stigma that foreigners will return and quit their jobs, which leads to a lot of difficulties in getting promoted ,etc.

Ive noticed that Japanese workers typically wear a white button up plus　jacket.　Is　it　okay　to　wear　blue　or　black　shirts?　Is　white　generally　considered　the　most　professional color, or is it simply japanese people not wanting to stand out? Will I label myself even more as an outsider if I choose another color?
