在移民/公民申请进程中，假如地址/联系方式有所变更，该如何通知给移民局呢？
首先，你要明确具体什么时候通知移民局地址的变更为宜？请尽量在搬家之前3周通知，以保证移民局信件顺利到达新地址。
有哪些方式可以变更地址呢？
申请人可以在线online或者通过IRCC网站的web form变更地址/联系方式。
通过Online方式变更地址时，首先要确定自己属于三中类型中的哪一类申请人：
一类是在在加拿大境内递交的移民申请，
第一步确认自己是否可以在线变更地址：
Step 1 – Check if you can change your address online
You can use the online service if:
- your case is being processed in Canada
- your address is in Canada
- you are moving within three weeks or have already moved
- you must also have either:
- sponsored a member of the family class,
- applied for permanent residence from within Canada,
- applied for a Permanent Resident Card,
- applied for Canadian citizenship (for yourself or for a person adopted by a Canadian citizen),
- applied for a citizenship certificate (proof of Canadian citizenship),
- applied to renounce or resume Canadian citizenship, or
- applied for a search of the citizenship records.
第二步 手边准备好申请相关的文件，以便填写在线信息
Step 2 – Gather your documents
You may need documents related to your application, including one or more of these:
- a copy of your application
- your fee receipts
- any letter or official document we issued to you
第三步 在线变更地址信息
第二类是在美国境内递交的申请
如果你是在美国境内递交的申请，可以通过联系Canadian Visa Office 在线变更
第三类是在除加拿大和美国以外的国家递交的申请
同样也是联系Canadian Visa Office 即具体的使馆进行变更。
一般情况下，如果申请案件还没转到具体使馆，可以直接通过IRCC的web form变更地址即可，如果案件已经转到具体使馆，则可以通过Canadian visa office变更。
如何查看地址是否已经更新
5个工作日后，可以通过Address Notification 或者Change of Address 查看地址的update。
