Need help.. Could Intensive stuttering therapy benefit me??

Need help.. Could Intensive stuttering therapy benefit me?? Hi everyone. I have been thinking about going to an intensive therapy program (the speech and stuttering institute in Toronto Canada) for a while. The problem is I am not from Canada so its going to be a little difficult and expensive for me. Applying for visa, ticket, stay, therapy fee, all put together its not going to be cheap. I was wondering if its worth it. Has anyone been to this particular program or any similar one? If anyone has any input or suggestion, it doesn't matter if you have had similar therapy or not, please feel free to offer it. It could really help me make up my mind. Another question, since English isn't my first language and the program is in English, do you think it could be less effective for me when I try to speak in my native language back home? ( Apologies in advance if you think thats a stupid question)
