Reading the Visa application on UKBA can I confirm that my wife to be will need to apply and fill out the VFA4 form online as apposed to printed PDF docment filled in by ball point pen.

How to apply

To apply for a visa, you must:

complete and submit a visa application form online; and
visit our visa application centre in Manila or Cebu (applicants who wish to lodge their application at the visa application centre in Cebu must pay an additional service fee of 3,900 Philippines pesos. The fee is payable in cash at the centre on submission of the visa application).

You will need to print out and sign your completed form. If you do not have access to a printer when you apply, you will be able to log in and print out the form later.

You can find the online application form under 'Do it online' on the right side of this page.

When you have completed your online application, you will receive an email message containing your application number (also known as a 'GWF reference'). Please make a note of this number.....

Many thanks John

PS Could I pay the fee for my wife using my Visa card?
