I wish ...

I wish i have never met you.

I wish i have been in Mexico.

I wish i were/was in Mexico. = This means that i want to be in Mexico right now ?

are they correct ?
, thanks

“I wish I had never met you.”

“I wish I had been to Mexico.” – usual way of saying that you wish you had visited the country (at any time in the past)

“I wish I had been in Mexico.” – usually implies that you wish you’d been in the country at a particular time or for a particular occasion

“I wish I were/was in Mexico.” – you wish you were there right now. “were” is more formal; “was” is more conversational.

The word “I” is always capitalised, wherever it appears.
