大虾帮我中译英一句话吧,c:由于您的work permit要到本月底才可以去办理延期,所以,您的visa延期也只能在(这个)做完后才可以去办理.

C: because your schools to permit until the end of this month to go to the extension, so, your visa extension also only in (the) finish just can deal with.

And because your schools to permit until the end of this month to go to the extension, so, your visa extension also only in finish just can deal with.

(1) Application to extend your visa can only be done after you have renewed your work permit at the end of this month.
(2) You must renew your work permit at the end of this month first before you can extend your visa.
(3) You can only extend your visa after you have renewed your work permit at the end of this month.

your visa extension application could only be handled by the end of this month because your work permit can only be handled by then.

As the extension of your work permit could only be applied by the end of this month,the application of extension of your visa could be done only after that.
