1-130 vs K3/K4
 

Can anyone tell me the *approximate* wait time for an interview for an I-130 in
Montreal once you've received the approval notice? And what the fee would be for
myself and my son? And just to clarify, is there not alot of fees once you've entered
on the K3 and K4 visas for EAD (if not received at POE) and AOS? We're at the point
of just waiting out the I-130 other than the K3/K4 visas to just have it all done and
said when we enter the U.S. Can anyone shed some light on this for me? Or direct me
to sites where I may research this information? Thanks Jo
