Well, I went to the NB session in Sao Paulo last Saturday. Had the opportunity to meet other forum members and have a beer. Maybe two...no, I think we had a little more.
In short, the session consists basically of a basic explanation of how Express Entry and NB EE stream work. Afterwards, another lecturer made a presentation of the province, talked about the advantages of living there, mostly due to their smaller cities, showed some pictures and data from Moncton, Saint John and Fredericton and went to a step-by-step explanation of how to submit an EOI after attending the session.
In the end, there was a short Q&A, with them promptly answering most questions for all the audience. After the session, the lecturers even talked to individuals in small groups to clarify a few minor doubts.
I was impressed by the informal way the session was conducted, even with some clever jokes. They were very friendly and helpful. Seemed almost like salespeople. Well, that's actually what they were doing there!
The session lasted a little longer than one hour and half and we just got some brochures and a pen. There was no certificate, as they have a record of everybody who attended and you just have to mention the session and date on your EOI.
