Using QGIS 2.4
I am currently importing a csv file with ~30,000 polygons (polygons in WKT format). I also have a United States shapefile. I have used the Clip function to get only the polygons that are in the US. When I go to save the new clipped shapefile as a CSV file with GEOMETRY set to AS_WKT, sometimes the number of lat/lon points is very long and so it cuts off, not finishing the polygon or multipolygon. Is there a way to set the export to include all points?

I know this question is old of more than two years, but it didn't receive an answer till now, so I tried to answer it although it might be out of your interest.
I tested your data and I didn't have any problem of exporting the new clipped shapefile as a CSV file with GEOMETRY set to AS_WKT. Here is the process of what I did:
Vector -> Geometry tools -> Multiple part to single parts
Vector -> Geoprocessing tools -> Clip
and used small polygons as input file and selected US boundary as clip polygon, as you can see below:I tested using QGIS 2.14.5, so maybe there is some improvements in the performance of exporting the shapefile to CSV with GEOMETRY set to AS_WKT, compared to QGIS version 2.4.
