<prompt> Human: My sister moved to Chicago IL August last year to pursue her Masters in engineering. As soon as she got a part time job with the university, she opened an account in Chase bank because they offered a 300 signup bonus. The only string attached as per what she told me is that, you need to have the account open for atleast 6months and cant close it before that. Her reasoning is that all of her friends did it for the free 300, im not convinced. Can anyone give some insight to this andor if theres anything she should be vary of?  <response>: Its safe. However, unless she sets up a monthly direct deposit to the account or keeps a minimum balance with Chase, she will have a recurring monthly fee.
