如果你想邀请别人留学时陪伴你，你可以这样表达：
```
I am eager to have your companying during my studies abroad. It would mean a lot to me to have a friend like you by my side as I navigate through this new and exciting chapter in my life.
```
或者更简洁一点：
```
I would be grateful for your company while I study abroad. It would make the experience more enjoyable knowing I have a supportive friend like you with me.
```
希望这能帮到你，
