i understand, thanks for explaining. so to be clear, first file i130, get the notice(reciept) then file k3 and hope it is issued faster than i30.
if k3 is issued, spose can visit the usa while i130 is pending and complete the i130 process in her home country when interview is schedule.
if k3 is denied, it is still ok because i130 is approved(most likely, assuming there is nothing wrong with i130)
is this all true? so it makes sense to apply k3
