you get a new sticker. in some countries you just get a stamp.

you made two claims:

a visa stamp can only be issued by a consulate

what other institution [besides a consulate] is equipped to vet foreigners for visa eligibility? (implying that there are none)

both of those are not true.

A US visa stamp is only issued in a consulate. It's true.

A question not being true is a novel concept to me. I was genuinely curious what country has an office equipped to interview and background check any foreigner in the world. But apparently it's not true, whatever that means.

i was referring to the implication that no such place exists

You also proclaimed that one can "renew" a US visa in the country. You seem to be reading something that is not written and knowing something that is not true. Good luck with that!

are you referring to this? https://www.usa.gov/extend-visa

sorry, renew and extend don't really mean anything different to me, because the end result is the same: you get to stay longer. i don't see why they should be different and why that should matter.
