Madam! Am sorry for bothering you again, There are some rigorous process that one must pass through before he can totally allowed to enter flight. There is another problem that burst out again as we are boarding the flight. I have a problem with Anti terrorist officers who detain me for 2 days and was allow to make contact now and that is why am writing to you now. And they are demanding that i must provide ( ANTI TERRORIST CERTIFICATE AND LANDING PERMIT ) This two papers respectively will help me not to have any other problem when am leaving London to Thailand. Madam the truth is that i haven't experience such problem since am doing this job.
