I am interested in attending a Six Sigma green belt course, but can you please advise me the difference between IQF and ASQ? Are they both approved in Dubai and Worldwide?

ASQ is acknowledged worldwide and content is quiet exhaustive and covers all the tools of Lean Six Sigma whereas IQF doesnt have any history or background with regards to its credibility, it has been created  and run by 1 person and by the same intitute which provides training on Six Sigma. Also whenever you look for qualified institute for training or certification look at the Body of Knowledge ie content .. its presence world wide and instructor profile in terms of practical experience of deployment as Lean Six Sigma is not an educational course, it’s all about practical application of the tools used in Lean Six Sigma.. you can also refer to IASSC(International Association of Six Sigma Certification) , as their BOK covers almost same BOK as ASQ… hope this answer helps you with your decision..
