Student to Stamp 4 Base on Child

Dear Members

I would like to asked if Student Hold valid stamp 2 and have Irish Born Child hold a Irish passport so can Student get stamp 4 ?

What is the process?
Did She need to apply Zambrano application ?

Or She can get Stamp 4 from immigration office on window.
I Really Thanksfull to all Senior Members if they assist on this matter.

Thanks

Following a landmark judgement from the European Court of Justice in March 2011, in the famous case of Ruiz Zambrano v Office National De L’Emploi, Case C-34/09,  which established the derived rights of non EEA parents of  Union citizen child to reside within the territory of the EU, the Minister for Justice set up a scheme whereby non nationals can apply for stamp 4 residence permission on the basis of their Irish child.
Non nationals who are currently residence in the State on the basis of lawful residence permission can attend their local immigration office directly, with their Irish citizen child, and provide their passport and GNIB card, the child’s passport and birth certificate. They can then be issued with a stamp 4 permission immediately without need for a written application to the Minister for Justice

According to this Judgement you can get stamp 4 without applying Zambrano application.
