我拿到体检通知了:)

各位前辈,我今天收到使馆来信,要求体检,并交登陆费(RPRF),有几个问题想问一下:
1...Based on the information supplied,we anticipate being able to finalize your application without a selection interview within the next 6 months.However,please note,we may decide,at any point in the application process,that an interview may not be waived.是不是还有可能面试啊?
2.我如何交登陆费啊,我有亲属在加,可以拖亲属办吗?
3,体检需要做什么准备呢,要带什么资料吗?三张照片和以前递交使馆的不同底可以吗?
谢谢!!!
