The immigration interview was approved immediately. Can I stop logging in?

The immigration interview was approved only to get a visa, but the visa was valid. If you don't log in within the validity period, it is equivalent to automatically giving up immigration opportunities. Therefore, you need to log in once before the visa expires to activate the immigration process.

If you lose your passport before landing, you will automatically give up your immigration opportunity and need to apply for immigration again. Take care of your passport!
