meeting child before filing I-800

From reading the state dept site, it seems vague to me, and that either option would work. I've seen two different scenarios offered by different agencies (for Poland). One is that we would make a first trip, meet the child, officially accept the referral (I guess confirm acceptance really), return home and file the I-800. This would result in a 2-4 month wait before we'd have the court hearing scheduled and travel for the second time for about 6 weeks (including bonding time). The second scenario is that we would file the I-800 upon acceptance of the referral, prior to travel. We would then stay for 6-8 weeks, do the bonding, court, etc., and return with our child, having only made one trip. I was expecting Hague to require meeting the child before accepting referral/filing I-800 (Polish law requires a meeting before this committment), but the wording on the state dept sounds to me like either option would work. Which one of these is incorrect? Or are both valid?
