B: Sure.what is it about?
A: My friend Tony has just finished his formality of entry into Singapore; he will be staying there for maybe a week or so to go on sightseeing there. Now he is worrying about his departure from there because he has no idea about the departure formalities. You know it very well professor.don't you?
B: Well.l can tell you something about it.but I am afraid what I am going to say is just the general situation.since even] countrlt has its own way to deal with the problem.
A; OK,I've got it.
B: Generally speaking.foreigners are allowed departure as long as the departure regulations and restrictions of the host country are satisfied.There is no reason for the host country to detain a foreigner. So tell your friend not to worry too much. It is easier to leave than to enter.what do you think?
A: Yes.l guess so.
B: But tell your friend to remember one point.that is almost all countries have such rules that foreigners can not leave the country until they do not have unsettled judicial cases.debts,unpaid duties.besides they must go through departure formalities before they leave.
A: OK.I will.
B: Oh.l forgot a very important point.if the host country finds that the foreigner threatens the country as well as the people .the host countrlt has rignts to ask them to leave.or expel them for the sake of public order or safety. But the host country would not abuse this right.
A: OK.Thank you very much,professor.l will tell him what you said,
