i submitted mine july checked mails and junk for weeks in the end i went onto my embassy acct and there it was it said been approved few days after application and confirmation email had been sent but id never got it...if youve applied via your embassy acct keep checking that
From what ive tried to research before the 60 day came in you could go in for 30days 3 times in any 6 mth period...now im unsure if that is still the case but i feel sure with the new 60 entry even if you extend another 30 each time you can only entry that way 2 times in any one year period
