you dont need to fill in the guarantor section if you're using your own bank account with 500k and above funding. The guarantor section is only for those who need others' bank account to be presented at the bank
I'm not sure what is their standard. But mine was 500k++ that sit still in the bank for 3 months and I used foreign bank account and my account was 3 months old
well tbh though.. I think if you go early, you might need to queue.. I arrived at 1:30pm ish so it was pretty much just me and 2 other people who were there 😅😅
