bounced checks unpaid

hopefully you can help to this problem really quickly because its really important PLEASE

so i have a friend that issued a check for 10K about 5 or 6 years ago and bounced, i don't know how much did my friend issued. and because of financial problems and work problems my friend couldn't pay, so my friend applied for a citizenship in another country. my friend sent some payments to relatives for them to pay , my friends' relatives made the first couple of months payments but soon found out that the relatives stopped making the payments and kept the money for their needs. so my friend stop sending money. my questions is.....my friend is now planning to go back to the philippines and now my friend a citizen of another country for almost 5 years, could there be a warrant of arrest and is there a chance of jailtime?.....thank you so much and i appreciate your answer in advance =)

before she arrives, make an inquiry at the Bureau of IMmigration if your friend is on the derogatory list. if not, when he gets here, file for an nbi clearance and that's when you'll know if he is facing a case.
