I just found out I can log-in E-CAS now, but my status of sponsorship changed from "Decision Made"(before the E-CAS is down, and I received DM letter in August last year) to "In Process", and when I clicked "In Process" the page shows exactly the same info as I saw before with "Decision Made". the status of main applicant(my wife) remains "Application Received". Should I be worried about this change? Can they really reverse the decision of my sponsorship?
