<prompt> Human: I left my prior workplace for a government job and have 13k sitting in my 401k. The gov jobs offers a TSP thrift savings plan option which is similar to a 401k. They were unable to tell me if this can be rolled over. If not, what options should I consider? A roth IRA?  <response>: As a government employee and contributor of a TSP, you absolutely roll your old 401k into the TSP. The TSP is awesome and the fees are some of the lowest around.
