Tesol or Celta

hai, i have an intention to become english teacher. i knew few english courses offered in my place. i just miss a chance to do celta course which started in january end in july. another session is only starting in july. there is no other place offering it unless if you take it online. but tesol course start in march/april june with shorter duration usually end within 2 months. the course is available every 2 months. i'm not sure wether to wait till july to take celta or to enroll into tesol in march. which is better to do? i just want to make sure that i take the right course with international accredition which can allow me to teach english at any part of the world. i dont want to regret at mid of the course for wrong choice. and how about doing online celta program? is it worth? does it has same quality as doing full time attending class. how about getting job?does education institute/school can take those who completed d course online? could anyone advise me on dis matter. thank u
