You should put today's date -- that is, the date you are filing the form. If you handwrite any answers, they will not be readable in the new 2D bar code at the bottom (which changes as you type things in) and the form will have to be manually processed, slowing down the process.
If possible, use the word "present". Otherwise, use today's date.
Mr. Shusterman's (former INS Trial Attorney, 1976-82) response to your question is general in nature, as not all the facts are known to him. You should retain an attorney experienced in immigration law to review all the facts in your case in order to receive advice specific to your case. Mr. Shusterman's statement above does not create an attorney/client relationship.
