@Steven **************
we are talking about 2 completely different scenarios here.
U were doing a border bounce.
Basically "activating" another 90 days of a visa u already have, and is valid for a year.
He isnt.
He would be using a 30-day exception scheme which is what they r becoming tougher with nowadays.
Basically he has no visa and to the Singapore eyes he is abusing a system.
Whereas u have a long stay visa.... married to a national...
The credibility of the story is vastly different.
Yes: i couldve just had bad luck.
Then again... outta of all options, it would be my least favourite.
