请教大家两个问题：

1 IMM0008里第7项要求填CSQ号码，但CSQ上有两个号码
一个是individual reference number
第二个是 numero du dossier
大家填的那个呢？

2 $490费 Right of Permanent Residence Fee
The Right of Permanent Residence Fee, which will be requested by the processing office at a later stage if your application is approved.
官网上说批准后再付，那大家有没有开始就交掉的呢？

谢谢了！
