unable to pay loan covered by checks in qatar

hi atty. pls. advise me about my predicament.
i worked in qatar 2 yrs. ago & got a loan w/c i am supposed to use in constructing my home back in RP & i issued pdc's. while i'm on vacation in RP i got sick & hospitalized for months. i was not able to go back to qatar and my employer terminated me. the money i loaned was used for my hospitalization instead of my house construction. now, the bank told me that they filed criminal charges against me & that i will be held in any airport immigration. also, a certain Filipino is now calling me (i'm sure he's calling from RP) that they will file an estafa case. i don't know if he is a collection agent or from immigration or something.

Atty., i'd like to go abroad again since i'm healed. what are my chances of being held in the immigration of another country? what about the estafa case that this certain countryman is telling me, will it prosper? will my record at the nbi be affected?

qatari law cannot be enforced here, and i really doubt they will go through the effort and expense to get your extradited. criminal law is territorial.

if you wish to check if your are in the derogatory list, contact the bureau of immigration. i do not know what will happen at foreign airports.

thank you atty... but what about the collection agency (i suppose), can they file a civil case against me here for non-payment? can they secure a warrant of arrest? can they go after my properties? pardon me for my ignorance on the process of the law

yes, they can file civil case here and go after properties in your name.
