On my double entry tourist visa I'm on my second entry and already done the month extension (for the second time) taking me close to a total of 6 months.

Is it true I can extend for another 7 days on top of this? If so is the process the same for the month extension, ie passport picture required, B1900 cost etc?

Also, can I do this at any time, eg 3 weeks before current expiry?

I'm an Australian passport holder.

Thanks.

They can provide a 7 days to leave for normal extension application fee but believe time may start on day requested and may also require show of outbound ticket.

Normally 7 days to sort yourself out and leave.

Starts on the day you apply.

OK, thanks very much.
