Gift tax from foreign parents

[Martingale Kim]

my parents in law want to give us $60,000.

i know there's a $16,000 gift tax limit. 

so to qualify this limit, does my parents-in-law need to wire me and my wife respectively 4 times at $15,000 each time?

what will be the form to file it in my federal and MD tax return if it is needed?
