我上个月同时递交的140和485, 至今未收到收据,律师也未收到. 但是从支票背面看到receipt number. 上ins网查询发现485的收据收到。但查140的status时，却说“Status for this Receipt Number cannot be found at this time in this automated system. Please check your case receipt number to see if it is correct. If you have questions or concerns about your case status, please contact the service center where you submitted your application.". 请教有识之士，这代表什么，我应该怎么做？
