Can I re-apply if my 35-day multiple-entry Singapore visa expires?

A multiple-entry visa can ensure that you enter and exit Singapore multiple times, but it is best not to exceed 3 times, otherwise you will be questioned when entering Singapore. If there are any questions, you may be refused entry. The last date of entry must be the last day of the visa validity, which is August 6th. You can stay for another 35 days after entering the country on August 6th. But in your case, it is unlikely that you will be able to stay in Singapore from the time you enter the country on August 6th until you leave Singapore on the 15th. So you must apply for a new visa to ensure that you can enter Singapore and fly to China on August 15th

If a visa cannot immediately apply for a second visa within the validity period, you must wait for the previous one You can only apply for a new visa after it expires. So you can only apply after August 6th. There should be many Malaysians in Johor Bahru who hold Singapore green cards or have become Singapore citizens. If you have such a situation, ask them to help you apply on the ICA website. The fastest way is to issue the visa the next day and the procedure is simple. If you cannot find it, you need to find a travel agency or go to one of the Singapore embassies and consulates in Malaysia to apply.

You cannot enter Singapore after your visa expires, so you cannot apply for a visa at the Immigration and Checkpoints Authority
