How can I apply for 13 (a) visa?
Ask for an application form (Form number RBR 98-01) from the Public Assistance Unit of the Office of the Commissioner Window One (1) or from the Makati Extension Office and accomplish the form properly. If you will be accompanied by your unmarried minor children they must fill up a separate form.
All documents to support your application must be properly certified as true copy. Sworn statements or affidavits should be notarized.
Foreign documents must be duly authenticated by the Philippine Embassy or Consulate at the place where they are issued.
You may submit the duly accomplished application form with the supporting documents to window (1) located at the ground floor of the main building of the Bureau of Immigration or to the Makati Extension Office.
NOTE: Filing fee should first be paid before an application is filed.
***Yes it is not too costly to apply for 13(a) visa but the process is too long and tiresome,you need to provide documents supporting your documents above like ..NBI ,Barangay clearance,a statement to prove that both you are living together as husband and wife(accommodation),health clearance like chest Xray , all the affidavits to prove that your husband has the capacity to support you financially and these affidavits should all be notarized or certified by a solicitor.
after the applicant submitted all the documents ,the partner who is a filipino citizen may be called for an interview to determine if she really agree for his/her alien spouse to stay as a resident..and wait for another more weeks for the decision or approval from the Bureau of Commissioners. ***
