我老婆（PR）为我申请绿卡
她同时要为我做经济担保，家里就我们两人，不知道为何计算结果会出现3人
10. Enter the total number of immigrants 填1吧
PART5. household size
21.a. Enter the number you entered on line 10. [1]
a那里一定要填1吧
b. Yourself. [1]
c. If you are currently married, enter "1" for your spouse. [1]
c也要填1吧
这样就household size变成3人了，怎么办呢？
PS，我老婆去年的收入不足，所以我也找联合担保人填了另一份864
先谢谢各位了
