The announcement then delay is a negotiating tactic in the contest with the House. There is not the manpower to do the sweeps without using the military to go through neighborhoods and that is all forbidden by Posse Comitatus.

Posse Comitatus is applicable to citizens, not invaders.
ICE is constantly gathering up and deporting people, they use information gathered at processing like relatives and friend’s names, addresses, phone numbers. They knock on certain doors, looking for specific people that they have deportation orders for. Same way other LEOs gather criminals.
When they do big raids they plan ahead and have far more manpower and are able to gather more people. That level can’t be sustained 24/7 but it does serve to make illegals watch over their shoulder and be afraid to build a business, buy a house, avoid long term plans. Many even self deport when there are big raids.
