Juba and Khartoum .. A Test to Immigration Rules

With the advent of the 9th of April as the deadline for the Southern Sudan citizens staying in Sudan to legalize their status as they will be considered as foreigners and will be treated according to the immigration laws, the Southern Sudan government seems to be worried and wants the extension of the deadline set by the Sudanese government.
The Minister of Interior says that the deadline is final and it has the entire jurisdiction and options to deal with this issue. In fact, the Southern Sudan government fears that the Sudanese government will adopt the tit-for-tat principle as the government of Southern Sudan has forced the Sudanese people in the South to leave it.
Perhaps, these fears were the main reason for the request to sign the four-freedom protocol by the South Sudan delegation that avails the citizens of the two states the freedom of movement, possession and work in each country.
Obviously, the fears of the South Sudan government are motivated by its wrong doings not by any other bases.
Since 2008, and even before the secession of the South, the government of South Sudan adopted a systematic policy of liquidating the economic activities run by Northern traders. The Southern Sudan had adopted a policy of imposing levies and heavy taxes on the Northern traders to force them to leave their business in the South.
According to statistics by a Sudanese organization, the SPLM Army has killed thousands of Sudanese persons during the period 2005 -2011.
In addition to that, the SPLM has abducted thousands of Sudanese children ranging from 2000 to 5000 from Darfur, Blue Nile and South Kordofan and sent them to the training camps in Unity and Jonglei States.
While Sudan is trying to legalize the status of the Southern Sudanese citizens staying in the North and easing the worries of the South Sudan government, the South Sudan government does not seem to be trying to do the same.
