我想推荐同学进学生会英文要怎么说

学生会正宗讲法从来都是student council
没听说过student union
union是联盟的意思
比如说trade union 劳工联合会，简称工会

所以应该是：
I would like to recommend one of my classmates to join the Student Council.

I'd like to recommend one of my classmates to join the Student's Union.

I intend to recommend one of my classmates to join the Student's Union
