Hi~

This is Teacher Rach~ Here's your correction:

Living as a foreigner is not a simple matter.

There seems to be so many things to watch out for. 

==> There seem to be so many things to watch out for. 

Everything I thought before I came to the Philippines was an illusion. 

There is no simple life.

• 'seem' should be in plural form since the subject of the sentence is not 'there' but actually 'so many things'.
