我上新加坡的官方网站都没找到任何声明大陆护照持有者可中转免签的文字,只有在新加坡移民部网站的fqa里找到以下一段模糊的有点曙光的文字:q:i have an onward connecting flight from changi airport. do i need to go through immigration clearance on arrival?a:visitors who have confirmed air tickets for connecting flights out of changi airport can remain in the airport's transit area without immigration clearance, unless directed to do so by the authorities in changi airport. however, if you wish to leave the airport premises and enter singapore for social visit or residence, you will need to appear for immigration clearance to obtain an entry pass endorsement on your passport. 这个可能便是2楼所说的被驻机场的官员引出机场的那种情况吧,但是时间限制这里没说,只能到了changi机场再具体问喽,估计最多是住一个晚上的时间.官方网站还说overstay要罚款!我也打算在新中转,幸好间隔不长
