How does is work for the child(under 18) of PR parents? do they need to wait longer period? when i did a search i found the need to wait atleast 4 to 5 years in general for most countries until the filing period becomes present.

Is that 4 to 5 years applicable to Nepalese too?

If anybody have similar situation or well knows the situation please drop your valuable thoughts, would love to hear it.
