The USA is the size of a continent, so perhaps a fair(er) comparison would be to add all the immigrants in Europe. That's ignoring the fact that most people don't migrate to the USA because it's immigrant friendly but because of other factors such as proximity, language, and economy, and ease of access. Living in the USA as an undocumented immigrant is not that great. The balance is also tipping at the moment (e.g. more people are leaving the USA than entering the USA, currently).
If you look at the figures for net migration per 1000 inhabitants[1], the USA and Germany are pretty much the same for the period between 2007 and 2012: 15.94 per 1K and 15.54 per 1K respectively. For 2017, the USA sits at 3.9 (Canada 5.70).
