从句子结构看，that you have to...应该是problem 的定语从句。

have to 之后缺少一个动词，我试着补充上，应该是“解决”或“处理” 等之类的动词。

In Kurdistan you have some problem that you have to solve, if you want to do business, if there’s planning and you give its billing.

In Kurdistan you have some problem that you have to resolve, if you want to do business, if there’s planning and you give its billing.

In Kurdistan you have some problem that you have to work out, if you want to do business, if there’s planning and you give its billing.

In Kurdistan you have some problem that you have to deal with, if you want to do business, if there’s planning and you give its billing.

some problem 中，some 表示“某一个”；

some problems 中，some 表示“一些”。
