I did my student visa in Kuala Lumpur, I'm gonna live in Chiang Mai, but I'm gonna travel to Bangkok first, is there some problem if I go by bus?

Thanks for your help guys

Sometimes they put the aircon and really low and its gets rather cold on the bus .

No problem.

 

Why do you think there would be?

I would travel by Train into Thailand, and enter at Kuala Lumpur.  The bus usually goes through Sadao, which is less-friendly - though you should be OK with a new ED-Visa.  After entering Thailand, you could fly out of Hat Yai domestic-air, or continue by-land (long ride, though).

 

Be aware that you can be asked to show 20K Baht worth of Cash or Travelers Checks (not plastic) at ANY entry-point to Thailand - land or air - but is reported most frequently coming by land from Malaysia (especially Sadao).  They ask to see the cash less frequently by air, but if they do, and you don't have it, that is cause for a refused-entry.

Very true.  Long pants and a sweater or hoodie are needed - even with their blanket.
