I'd appreciate some help here. I'd love to study in an English speaking country, as frankly the prospect of learning a new language up to fluency before applying for an MBA seems a bit daunting. English is my second language, but I speak it fluently. Considering that my funds are limited, I'm specifically interested in finding out about the countries that offer the best funding alternatives.

US then UK

MBAs are often taught in English even outside the English-speaking world. These can be in fairly inexpensive universities. Using MastersPortal you can select a low tution (say $2500 a year) and get dozens of options. https://www.mastersportal.com/search/master/master-in-business-administration?tr=[0,2500]&di=242&rg=1 

Thank you both. The link provided seems very useful and the fees seem up to date, so I think I'm going to go from there. 

Really depends on your profile, but if you are able to score high on the GMAT (e.g. >700 for good schools and >730 for top schools), you will generally get a lot of full scholarship (free tuition) offers from US business schools.
