Hi..I went thru some topic but couldnt find any info, apart from crossing land for 15days..My qns is do i have any option to get longer stay? Currently I am crossing land for 15days after my 30days was expired.

Tourist visa like most people use - they are even free at the moment but will require an overnight stay. Air return would provide 30 day stay without a visa.

You obviously are not working legally so that seems to be out as an option for longer stay.

You do not mention marriage or other tie to Thai persons.

You do not mention study of anything.

If you provide more information perhaps we could answer better but from what you provided tourist visa seems to be the best option.

I am not studying nor any relationship with a Thai girl. And I am not working here either.. So my only option is to get Tourist visa? even if Singapore PP actually no need Visa to enter Thailand?

Thanks for the reply btw.

Unless you like the 15 day visa exempt or want to do the 30 day by air version a tourist visa would be the logical choice for most people.
