Does that mean the student who applied for the EOI successfully still has a considerable possibility not to receive the Invitation to Apply (ITA)?

对方答复：
Good Afternoon,

Officers review the information provided in the EOI and make a decision based on the information provided.

If you’re a student that meets all the criteria of the program and you’re in the last three months of your studies, you will receive an ITA from the province.

Please note: receiving and ITA does not mean you will receive a certificate.

Regards,

NBPNP Team

请问最后一句receiving and ITA does not mean you will receive a certificate.指的是什么猫腻吗？如果都申请人条件都符合了，发了ITA后，官方还会找什么借口，比如不符合当地市场紧缺职业啥的来拒到学生吗? 总觉得这个政策只是为了吸引学生去读书，但是移民却暗地里设置门槛。 谢谢
