Hi everyone, I finally used my day off to start preparing papers for my work visa renewal, but I came back more confused than before 😅 I have the list from my company, but some document names look similar and I’m not sure which office actually issues them, especially the income/tax related ones and the employment proof. My company admin is kind, but they also told me to “check outside office” for some papers, so now I don’t know where to begin. For those who already did this, how did you figure out where to get each document?
