AP and reasons for leaving the country

[popple]

I am putting in my GC application within the next 2 weeks and am also putting in an application for AP. I really need this for June as my sister is getting married. In the question regarding reasons for requesting advance parole and provision of evidence for this reason, does "My sisters wedding" suffice? How can I provide evidence for this? Will it even be considered an acceptable reason to leave the country whilst waiting for my application for GC to go through?

Thanks

Despite what the form says about needing an urgent reasons, this is not true. Just put down on the paper a statement from yourself, explaining that your sister is getting married and I am pretty sure you will get your AP in now time
