When will one be able to

Question

How do you say "When will I be able to go to China?"

After trying to figure out and failed, I tried to translate the sentence from Korean to Chinese and came up with this : "什么时候能去中国?"

Now, the questions are:

• Is that correct?
• Why is there no question marker (such as 吗) in the translation? I wonder when I should use 吗...
• When are we allowed to omit question marks?
• And why is it using 能? Shouldn't it be using 会? Since 会 is more related to future possibility.

Answer 1

First, it is correct, yet not precise, it is supposed to be

我什么时候能去中国？

Second and third, there is no question marker because "什么" already implied that this is a question, you would use "吗" when it is not obvious if the sentence is a question

我能去中国吗？

Last, "能" corresponds to "able" in original expression. You use "会" for possibility, like

他什么时候会去中国？

This means "when will he go to China?".
