Yes, see ICA - Apply for Permanent Residence and in the Form 4A (http://www.ica.gov.sg/data/resources/docs/PR Services/Form 4A with IRAS Consent Form.pdf), when you fill your spouse and children's information you need to also indicate whether they are applying together with you. But be aware of your son's liability for national service if he should apply together with you.Applying for my SPR, question do you know if I can apply the same time for
My wife and son
As per the webpage above, you parents would not be eligible for PR until you are able to obtain citizenship, though they can still be on the LTVP in the meantime.And/or
My parents who are in Singapore with LTVP
Thanks in advance!
