SQL Missing left/right parenthesis

I keep getting a missing right or left parenthesis error when I try to create my tables with a foreign key, but when I remove the foreign key my code has no problem creating the tables. I need the code to run with the foreign keys.

--deletes respective tables previously created
drop table DEPARTMENT;
drop table POSITION;
drop table EMPLOYEE;
drop table COMPANY;
drop table DEGREE;
drop table GRAD_INFO;
drop table STUDENT;

CREATE TABLE Department
(
    Dept_Name varchar(255) PRIMARY KEY, --primary key
    Dept_Phone_Num numeric(35) not null
);

CREATE TABLE Position
( 
    Position_Name varchar(255) NOT NULL PRIMARY KEY, --primary key
    Position_Salary decimal(10, 2) not null, 
    Employee_num numeric(35) not null,

    CONSTRAINT fk_Dept_Name 
        FOREIGN KEY Dept_Name REFERENCES Department (Dept_Name) --foreign key

CREATE TABLE Degree

CREATE TABLE Gead_Info

    Grad_Status VARCHAR(255) NOT NULL PRIMARY KEY, --primary key
    College_Name VARCHAR(255) NOT NULL,  
    Num_Of_Degrees NUMERIC(10) NOT NULL,  
    Grad_Date NUMERIC(6) NOT NULL,

    CONSTRAINT fk_Degree_Type 
        FOREIGN KEY Degree_Type REFERENCES Degree(Degree_Type) --foreign key
);

CREATE TABLE Student
( 
    Student_ID NUMERIC(10) NOT NULL PRIMARY KEY, --primary key 
    Student_FName VARCHAR(20) NOT NULL, 
    Student_LName VARCHAR(20) NOT NULL, 
    Student_Address VARCHAR(20) NOT NULL, 
    Student_Email VARCHAR(20) NOT NULL, 
    Student_Phone_Num VARCHAR(10) NOT NULL,

    CONSTRAINT fk_Comp_Name 
        FOREIGN KEY Comp_Name REFERENCES Company(Comp_Name), --foreign key
    CONSTRAINT fk_Grad_Status 
        FOREIGN KEY Grad_Status REFERENCES Gead_Info(Grad_Status) --foreign key
);

The degree table is the only table where I don't get an error.

Should I use an alter table instead after I create all the tables or is there another way to solve my problem?

edit: updated code
