I would send both away, as one slot left is meaningless because there will be more than one boat. Further more, any illegal immigrant, irrespective of country will be sen home and their country handed the bill. Any foreign aid to those countries will be reduced accordingly, if it continues it will get cut off altogether. I work will several people who have immigrated from India, Pakistan etc who are excellent at their job. They followed the correct process to immigrate here.
There is a legal process to enter the country, if you don't respect our laws enough to obey them, then you shouldn't be here.
