<prompt> Human: Hey everyone!First of all, Im not sure if its okay to ask this hear. So if this has to be taken down I will understand it.My dad recently called me about how he got a check from the government dating way back to the mid 2000s. However, its named to both my dad and mom.The issue with this is that my mom never became a US citizen or resident. She was there with TPS. Ive been living with her for almost a decade in a foreign country and she never tried to get a VISA so she cant just go there for a few days and sign the check. My dads been told by various people that he can either get a vehicle from a dealership, cash it at a gas station or open a bank account in my country with the check foreign country in Central America.Ive told him to wait on all the option as none of us know if these methods are legal or could work.Whats the best thing my parents could do? Does my momdad have to travel to get the signature?EDIT: The countries involved are Nicaragua mom and I and the United States dad.EDIT 2: My dad sent me a photo of the check. It says Pay to the order of his name moms name.The only date I can make out on it is 122005 and it shows 01 29 18 on the first line. He just recently got this mail as he came to visit us on February 1st and returned to the U.S on March 8th. He got the check on March 9th.UPDATE March 13th, 2018: Thanks everyone for commenting and helping us out with this, I know I posted limited information and tried to answer as many questions as possible.My dad told me he called the IRS and the check is valid, with an Issue Date of 01 29 18, it was most likely sent to him a few days later, but unfortunately, he left the US on Feb 1st for Nicaragua to come visit us, thats why he got this check until these days.Hes decided hell come to Nicaragua to open a bank account here jointly with my mom, as the bank requires both of them to be present, both signature and both fingerprints. Thank you all for the help, good day!  <response>: US treasury checks are only good for one year. Many banks wont cash or deposit anything older than 6 months. When did he get this check? Has your dad been paying his taxes properly? Is he getting scammed?
