NBC News reports 
That a growing number of Chinese immigrants are crossing into the United States without papers,
Often taking harrowing journeys through several countries
And modes of transport and using social media as their guide. 
CBP reported that,
In the past five months,
At least 4,300 undocumented Chinese migrants have been apprehended crossing the southern border,
Which amounts to more than double the number for all of the previous year.
