Confusing between [I have been] and [I have gone]?

[sunflower.baby]

Hi all, I'm not sure about the usage of 2 phrases [I have been] and [I have gone]. For example:
[1] I have been in Singapore. => that means i already came to Singapore for some purpose (travalling, business...) and the trip already finished.
[2] I have gone to Japan. => that means i came to Japan and i don't leave Japan yet.
Am I correct? Please advice me. Thank you very much!

Not so easy. There are a number of possibilities and permutations:

I have been in / been to / gone to Singapore before= I previously visited it. With 'I've been in/to', you could still be in Singapore, or you may have left; with 'gone to', you are no longer there (and with 'come to' you are still there).
I have been in Singapore for 3 years = you still live there.
I have gone to Singapore for 3 years = you habitually visit it or are taking up residence.
I have gone to Singapore = you are not here; you may not yet be in Singapore.

And there are probably other readings.
