Ideally it should be filled on the computer using Adobe Acrobat Reader. I can't think why you wouldn't be able to do this as Acrobat is cross platform and as long as you're version is up to date you should have no problems. I found that the Travel history form was the only one I couldn't fill and save but the rest were all fine.I am a bit confused. Should the form be printed out and be filled by hand or should it be filled using the computer as mine doesn't not permit me to fill in the computer? And i came across somewhere on the cic webite that it should be validated. And I know validation can only be done if it's filled in the computer. Pls help
Filling it in on your computer does 2 things: 1 - makes it so that all of the information is clearly readable (you don't want bad handwriting leading to delays and having your forms sent back!) and 2 it auto generates the validation barcodes that you need for submission.
In short: make sure that you have Adobe Acrobat Read on your machine and that it is up to date in terms of version and you should be fine.
