That sounds about right. I've entered 3 expense reports on 3 different dates. The one I entered on 4/11 was approved on 4/17, and the check was cut 4/25, so I'll get it in the mail next week. The second one I entered on 4/19 was approved on 4/25. No check has been cut yet, but should by next week sometime. The last one I entered on 4/25 has not yet been approved, but I have no doubts it will be. You don't have anything to worry about regarding getting paid by RQA as long as your expense reports(s) get approved, which usually take up to a week.
The only caveat to that was when they had that HUGEEEEEE candy recall last year. Sometimes the expense reports took two weeks to get approved and maybe another two weeks before the check was cut. But it was a HUGE job.
