How to start the sentence with "or" in Chinese?

Question

I assume a sentence that starts with or in Mandarin, something like the follows:

M: Where are you from?

F: Chicago.

M: No, I meant which city you are from in China?

M: Or did you grew up in US?

In these sentences, is it correct to just use 或 to start the sentence? I haven't seen the kind of usage of 或; I only saw it is used within the sentence, combining multiple related items.

M: 你是从哪里来的？

F: 芝加哥

M: 我的意思是你是从哪个中国城市来的？

M: 或，你在美国出生和长大了吗？

Or if it is not correct, how should I start the sentence with or?

Answer 1

the translation is fine, but if you speak it, that's pretty weird.

colloquially, we use 還是說 or 或是說 or 或者說

So, the sentences are better to be spoken like this:

M:你從哪來的?

F:芝加哥

M:我的意思是你是從中國的哪個城市來的?

M:或者說,你是在美國土生土長的?

for the most part, we add few redundancies to sentence to make it fluent.
