Okay as I have been out of the country since I last filed my extension I will go to immigration, file my TM30, cancel my my extension and show a letter from my school and then I apply for a tourist visa extension to get my 7 day final extension correct?  Is that the correct order to do it?

I have also just returned from my home country with a new passport will this cause complications? as my TM30 and old visas/extensions are all in my old passport not new one I returned to Thailand on. Thanks

Okay thank you that is good to know. Can I apply for the 7 day final extension at any immigration office or does it have to be Chiang Mai as that is where my extension is filed at? 
Do I need my TM30 to get the 7 day extension and when do I have to apply for the 7 day extra visa? Can I do that while my ED extension has a few days left to run or does it have to be on the last day of my extension valididity?

Appreciate all your help!

What visa would I apply for to get an extra 7 days? an extension of my ED or a new tourist visa?

Okay thanks. I have heard if I just leave and don't cancel formally at immigration I may face issues in returning to Thailand in future as a tourist?

Hi there

Im currently studying Thai at Chiang Mai but will be leaving Thailand in a few weeks. Can I just walk into the immigration and cancel my ED visa extension before I leave Thailand or do I need some paperwork from the school to do so? 

After I cancel, the date of my validity to stay in Thailand changes or stays the same? ie if I cancel 2 weeks before im due to leave/the end of my extension, will the date be the same after I cancel or do I have to leave within 24 hours of cancelling the extension?

Thanks!
