I am looking for doing it online as I currently live in Romania.
There are several things to consider when you're contemplating becoming a life and/or business coach. What type of certification are you looking to achieve? The International Coaching Federation (ICF) is the internationally recognized accreditation body for certifying coaches with several different levels of life coaching. The coaching industry is still relatively unregulated so be careful which websites/programs you choose to use. I'd suggest doing some research for a program that will fulfill the ICF accreditation requirements and then when you've gotten your courses done, you can apply and take the ICF exam for your coaching certification.
This is a personal decision and it will be up to you to decide, what fits your needs. You may want to also think about what areas do you want to coach in? What is your coaching space? Do you know about creating businesses, are you an expert in something? There are so many areas of coaching and honing in on what makes you unique in the coaching space can go a long way in helping you decide which coaching program fits your requirements.
