For me, I could hold basic conversations within the first month... and obtained "near native fluency" by year 4. Prior to that, I was technically "fluent", working as an interpreter,, but wasn't able to fully express my personality in totality with the same ease as I do w/English. By year 4, it all came together!

How difficult do you consider this language to be?
🤔Well, ASL lacks tone + written expression... so, that may make it easier for some people.
But, as ASL is as rich as other spoken languages, the ease/difficulty in learning it is a bit subjective. (ie I take to signed languages easier than oral/rural languages [I think my 👂are broken!])
