婚绿485 Seattle FO 2年多没有绿正常吗

友友们，我是2023年2月交的485，当时伴侣是绿卡，去年变成公民后我们upgrade了。
24年年初打指纹，然后24年三月面试，五月变成USCIS is actively reviewing the case。今年本来看USCIS官网看timeline, 说五月初就可以催了，但是五月初一刷，变成明年五月了。。。
至今未变。找议员帮忙催得到回复如下，感觉比较模板。请问有类似的小伙伴吗？求抱团取暖求建议
These checks are necessary to ensure United States national security and public safety interests. In some cases, the results of these checks require USCIS to perform additional inquiries or consult with other government agencies. When this is necessary, there is often some delay in resolving the checks, and it is difficult to predict when resolution will be completed. Please be assured that this case has not been overlooked. Once all checks are resolved, the application will be adjudicated and your constituent will be notified of the decision.
